‘The five components of yama are called ‘mighty universal vows’, as they are not confined to class, place, time or concept of duty. They should be followed unconditionally by everyone, and by students of yoga in particular, irrespective of origin and situation, with a reservation concerning cultural phenomena such as religious ceremonies, vows and vocations of certain people. They form the framework of rules on which society is based.
I believe that this universal approach should be applied to all the other component stages of yoga, without distinction of time, place or circumstances, to lay down the precepts of a universal culture’.Iyengar BKS Light on Yoga Sutras of Patanjali p. 143
