Satya, meaning truthfulness, is a key principle of Yama in Ashtāṅga Yoga. It emphasizes honesty and sincerity in thought, speech, and action. Practicing Satya fosters integrity and builds trust in relationships, contributing to ethical and harmonious living. It also involves refraining from deceit and aligning one’s actions with universal truths. By living truthfully, practitioners experience inner peace and self-confidence, forming a strong foundation for spiritual growth and Yogic discipline.
