Non-injury or non-harming (ahimsa), truthfulness (satya), abstention from stealing (asteya), walking in awareness of the highest reality (brahmacharya), and non-possessiveness or non-grasping with the senses (aparigraha) are the five yamas, or codes of self-regulation or restraint, and are the first of the eight steps of Yoga.
