The yamas are the first limb of classical yoga, five restraints regarded as a great vow binding at all times and places: ahiṃsā, non-harming; satya, truthfulness; asteya, non-stealing; brahmacarya, continence; and aparigraha, non-possessiveness. They are close to the Jain vows and the Buddhist precepts.
