Yama and niyam are the basic guidelines for aspirants. Yama entails five moral codes of conduct for interacting with others: Satya, truthfulness, at the levels of thoughts, speech and actions; ahimsa, non-violence towards others and also towards oneself; asteya, non-stealing, not coveting that which does not belong to oneself; aparigraha, non-hoarding; and brahmacharya, at the physical level it refers to celibacy; for householders, it implies fidelity.
