The first limb of Aṣṭāṅga Yoga is Yama, which refers to ethical disciplines that guide how we relate to others and to the world around us. These principles are not commandments or rules imposed from outside. Instead, they are observations about what supports harmony in human life. When these principles are ignored, conflict and agitation appear both externally and internally. When they are honored, the mind becomes naturally lighter and more peaceful.

Patañjali describes five yamas: Ahimsa (non-harm), Satya (truthfulness), Asteya (non-stealing), Brahmacharya (wise use of energy), and Aparigraha (non-grasping). These principles address everyday human behavior. For example, ahimsa encourages us to avoid causing unnecessary harm through our actions, speech, or attitudes. Satya encourages honesty and authenticity in communication. Asteya asks us not to take what has not been freely given, whether material objects, credit, or time. Brahmacharya invites moderation and intelligent use of personal energy. Aparigraha encourages freedom from excessive accumulation or possessiveness.

These principles are not about moral perfection. Instead, they help reduce inner disturbance. Every harmful action leaves a psychological imprint in the mind. When we act with aggression, deception, or greed, the mind becomes agitated and defensive. This agitation makes stillness and clarity difficult. The yamas therefore function as a stabilizing foundation for yoga practice.

An important aspect of the yamas is that they are practiced gradually and with understanding. The goal is not rigid control but increasing awareness of how our actions influence our own mental state and the well-being of others. Over time, practicing the yamas reduces conflict in relationships and softens the internal tensions that often occupy the mind.

For this reason, classical yoga begins with ethics before physical practice. A calm mind cannot develop in a life that is filled with unnecessary conflict. The yamas establish an atmosphere of harmony in which deeper practices of yoga can take root.
