Grounding
Patanjali, the father of classical yoga (Bryant, The Yoga Sutras of Patañjali), set out the five restraints as the fundamental principles of yoga: ahiṁsā (non-harming), satya (truthfulness), asteya (non-stealing), brahmacarya (wise use of energy), and aparigrahā (non-grasping). Posture, breath, and meditation are built on top of ethical ways of being.
This eight-limbed path goes by several names for one thing: Raja Yoga, the royal path; classical yoga; and ashtanga yoga, from ashta (eight) and anga (limb). It is the yoga of meditation, self-control, and mastery of the mind that leads, limb by limb, toward self-realization. One caution about the word ashtanga: today it also names Ashtanga Vinyasa, the vigorous flowing style developed in the twentieth century by Sri K. Pattabhi Jois, whose recent, modern history is traced by Mark Singleton in Yoga Body. The two share the word and the eight-limb ideal, but they are arguably not the same use of ashtanga: one names the whole classical path, the other a modern posture practice. The Styles of Yoga page follows that lineage.
Raja yoga is one of four classical paths toward the same self-realization, each suited to a different temperament: bhakti yoga, the path of devotion, to the divine or to purity; karma yoga, the path of selfless action and duty; jnana yoga, the path of self-knowledge; and raja yoga, the path of meditation and the eight limbs. The Bhagavad Gita is the classic source for the first three, Patanjali’s Sutras for the fourth. Arhanta Yoga keeps a plain overview of the four paths.
The yamas describe practices that can increase our awareness of our spiritual life and our interconnections while releasing us from karma, self-absorption, lust, and hate; sutras 2.35 through 2.40 name the fruit that arises as each restraint becomes stable in a person. The epics teach the same principles in archetypes: Sita’s truth carried to its edge, Bali knowingly releasing three worlds, Ravana seizing what can only be given. Those stories live under the Banyan Tree, and are searchable by relevant pose, archetype, and yama.
The philosophy of the Yoga Sutras is the foundation of modern yoga, and its history is a broken and rebuilt one. The text fell out of circulation for centuries before modern, and predominantly Western, practitioners extracted it, added to it, and raised it into yoga’s central scripture. David Gordon White traces that whole arc in The Yoga Sutra of Patanjali: A Biography (Princeton, 2014). Thenmozhi Soundararajan presses on a harder part of that inheritance in The Trauma of Caste (North Atlantic Books, 2022): the broader scriptural tradition these teachings sit within also cements caste, a hierarchy she names as Brahminism, so holding the yamas honestly means reckoning with that history rather than sealing the texts off from it. The principles are ancient, but how they are kept is remade and reinterpreted in practice.
The five yamas
The Gita lists ahimsa among the marks of knowledge (13.8–12), the divine qualities (16.2), and the austerity of the body (17.14). But it is a complicated principle. Arjuna refuses to fight and calls the refusal ahimsa. Krishna answers that the deepest harm can be refusing our own dharma (2.31–33). Ahimsa is a principle of discernment as much as restraint.
Donna Farhi warns that the hardest part of ahimsa is honesty about our own exceptions. Because the mind keeps defending its old positions, practice becomes, in her words, “a methodical and painstaking examination of where we have created convenient loopholes for ourselves.” Non-harming holds only where we stop exempting our own comfort from it.
Ahimsa reaches far beyond yoga. Jainism, Hinduism, and Buddhism all carry it, and each holds it to a different measure. Jain tradition treats non-harming as the standard against which every action is weighed, asking ascetics to guard even the smallest creatures and to watch the harm carried in a thought. Hindu and Buddhist teachings hold it as a central value bound up with reverence for life and often with vegetarianism, at a gentler degree of strictness; the emperor Ashoka urged care for living things in his third-century BCE edicts. In the twentieth century Mohandas Gandhi carried the same principle into public life as satyagraha, nonviolent resistance to injustice; Susanna Barkataki reads satyagraha as a fusion of ahimsa with satya, a truth-force in which non-harming is not the passive avoidance of violence but the active power to make change. The word is shared across all of them, and the demand it makes shifts with the tradition that keeps it. Kazu Haga, who teaches nonviolence in the tradition of Gandhi and King, extends this active reading by refusing to equate ahimsa with the suppression of feeling: “anger is a natural and appropriate response to injustice.” Nonviolence, on his account, is not the absence of anger but the discipline of directing its energy toward repair rather than harm.
Ahimsa also turns inward, and for many people that is the harder direction. The first person we harm is often ourselves, through a running verdict of not being enough. Tara Brach names this the trance of unworthiness, the lens of personal insufficiency that leaves us, as she puts it, unable to perceive the truth of who we really are, and she offers radical acceptance as its antidote: meeting our own experience with the same non-harming we are asked to extend to every living thing. Nonviolence toward the self is not self-indulgence; it is the ground the rest of the practice stands on.
The Buddhist teacher Jack Kornfield extends that inward turn one step further, into forgiveness. For him forgiveness is not condoning what happened but declining to carry it forward as fresh harm. Kornfield puts it directly: "With forgiveness we become unwilling to attack or wish harm to another." Set beside ahimsa, forgiveness is what keeps non-harming from hardening into a held grievance, the practice of not passing an old injury along.
In movement, ahimsa begins with our own journey: honoring our motion, our body’s signals, and doing no harm to ourselves with criticism, pressure, or comparison. It reaches the hands-on adjustment too: Teaching Body Positive Yoga treats asking consent before an adjustment as an ahimsa practice, and warns against the abuse of power under the guise of adjustments, so that no touch is laid on a body that has not welcomed it. In meditation, it is the gentleness that meets a wandering mind, each return to the breath made kindly. In daily life, it shapes how we speak to ourselves and others, how we handle conflict, and how we treat every living thing our day touches.
Ahimsa toward ourselves also means refusing the pressure to make the practice a performance. The accessibility teacher Sunaina Rangnekar puts it directly: “Yoga is not limited to full extension of the pose or being able to do a handstand. Yoga is more than asana.” Read at the scale of the wider culture, some teachers turn ahimsa into a critique of the industry that sells the practice. Jacoby Ballard sets non-harming against a profit-driven economy, writing that “ahimsa is a commitment to do no harm; capitalism steamrolls anything standing in its way, be it a union, environmental regulations, or trust,” and argues that asana divorced from the ethical limbs can end up causing harm rather than doing good. These are contemporary teacher and activist readings rather than the classical definition, offered here as one way the yama reaches past the mat.
Satya is speaking what is, and refusing to live inside a lie even when the lie is more comfortable. The Gita defines satya as carefully choosing words that are truthful, pleasing, beneficial, and do the most good (17.15). Truth and kindness travel together in this teaching so truth used as a weapon is not practicing satya. Susanna Barkataki widens satya past one’s own speech into deep, compassionate listening, the kind that lets suppressed truths emerge, so satya is as much about the voices we do not hear as our own. Marshall Rosenberg’s Nonviolent Communication is one practical language for holding honesty and compassion together in the same sentence.
Judith Hanson Lasater offers a plain daily test for this. Because Patanjali lists ahimsa before satya, truth is never meant to be told apart from nonharming, so before speaking she runs a three-part filter: “before speaking or taking some other action, you first ask yourself these questions: Is it necessary? Is it true? Is it nonharming?” Only what passes all three is worth saying. The near-identical popular version, “Is it true? Is it necessary? Is it kind?”, is often attributed to the Buddha, but it traces to an 1872 poem by Mary Ann Pietzker, “Is it True? Is it Necessary? Is it Kind?” in her Miscellaneous Poems; the underlying idea of guarding speech is much older and appears across traditions.
Similar to ahimsa, practicing satya in movement is being true to ourselves and our path. Whether that means using props or returning to our breathing, the goal is not to get to the most difficult pose, but to embody our felt truth. In meditation, satya is honest witnessing: seeing what arises as it is, free of decoration or denial. In daily life, it is choosing words that are true, kind, and useful together, and living so the outside of our life matches the inside.
Asteya reaches past objects into time, credit, attention, and another’s freedom. The Gita says one who enjoys what is given without offering anything back is a thief (3.12). The whole third chapter frames life as a cycle of offering; hoarding is theft from that cycle. Michelle Cassandra Johnson widens asteya to the economy we live in: in a culture that insists more is always better, non-stealing becomes a discipline of examining what we consume, take, and actually need. There’s research that backs up the concept: Dunn, Aknin and Norton (2008) found that when participants spent money on others they felt more happiness than when they spent money on themselves.
In movement, practicing asteya reminds us not to over extend ourselves and take from our energy that could lead to injury, not to steal another’s progress by comparing their journey to our own, and to share space so everyone has the same freedom to move. In meditation, asteya lets each breath be enough; grasping after a different experience steals the one that is here. In daily life, it means honoring people’s time, crediting ideas to their sources, listening without taking over, and taking from the earth only what can be returned. Susanna Barkataki extends asteya to yoga’s own inheritance: interrupting cultural appropriation, and crediting and uplifting the traditions a practice is drawn from rather than taking from a culture that is not ours, is itself the practice of non-stealing.
The Gita’s meditator sits brahmacāri-vrate sthitaḥ, steady in the vow, mind fixed and fearless (6.14). The brahmacarya discipline also appears in the austerity of the body (17.14), sometimes read as celibacy, and at the practitioner’s final journey (8.11). Broadly, in brahmacarya, energy is self-regulated and focused. Deborah Adele reads the same restraint as nonexcess, an attentiveness to the point where enough becomes too much, and treats celibacy as only one interpretation among several.
In movement, brahmacarya is the most direct principle guiding us to avoid excess in our practice and to focus on our self-regulation. In meditation, it is the steady vow of 6.14: energy gathered toward one point rather than scattered across every distraction. In daily life, it asks where our vitality actually goes, screens, worry, overcommitment, and returns it to what we most value.
The Gita’s meditator lives aparigrahaḥ, free of possessiveness (6.10). The liberated actor works tyakta-sarva-parigrahaḥ, all sense of ownership released (4.21). This is the yama closest to the Gita’s core instruction: we have a right to the work alone, never to its fruits (2.47), rendered by Barbara Stoler Miller as “Be intent on action, not on the fruits of action; avoid attraction to the fruits and attachment to inaction.” This is aparigraha at its subtlest: releasing not only our grip on things but our reliance on outcomes, the results we expect, the futures we plan for, and the way we need events to turn out, so that we can act fully and then let what follows be what it is. Michelle Cassandra Johnson turns aparigraha outward from the self: she reads dominant culture as running on a belief in scarcity, and non-grasping as the choice to trust abundance instead. Psychology has begun to measure the trait: Sahdra, Shaver and Brown’s 2010 nonattachment scale tracks it against adaptive functioning and wellbeing.
In movement, aparigraha releases yesterday’s pose: the body arrives different each day, and the practice meets it where it is. In meditation, it is the letting go inside every exhale, thoughts and states allowed to pass without being kept. In daily life, it is releasing our expectations of a specific outcome related to our possessions, plans, and the people we interact with and love.
