Question to T Krishnamacharya:
“Can you explain the concept of vinyāsa and pratikriyāsana?”
“The question asked relates to Yoga and not to vidyābhyasa. There is no āsana without vinyāsa. Yoga is an experience, āsana is the third of the eight limbs of Yoga and it is also important to pay attention to first two limbs, namely yama and niyama.
One who wishes to enquire into and understand vinyāsa should first know what is āsana. According to Patañjali Yoga Sūtra, āsana is defined as “sthira sukham āsanam”.
sthira – Namely firm and without disease and sukha – pleasant and comfortable. To be in sukha state, all parts of the body should be in perfect harmony. This is true for all, whether one is a man, woman, deaf, mute, blind or even for animals. Any action that disturbs this state of harmony should be followed by a pratikriyā to restore the harmony. One cannot but accept this principle.
