Yamas are the great, mighty, universal vows, unconditioned by place, time and class.
The five components of yama are called 'mighty universal vows', because they are not trammeled to class, place, time or notion of duty. They must be followed unconditionally by everyone, and by students of yoga particularly, irrespective of origin and situation, with a reservation concerning cultural phenomena like religious ceremonies, vows and vocations of certain people. They form the skeleton of rules on which society is grounded.
It is however of the belief that this universal approach should be applied to all the other component stages of yoga, without discrimination of time, place or circumstances, to lay down the principles of a universal culture.
