Interconnection of Mind and Prana
Interconnection of Mind and Prana and their controlling through Pranayama
Chale vate chalam chittam nischale nischalam bhavet /
Yogi sthanutvamapnoti tato vayum nirodhayet//(Chapter -2, Verse 2).
When Prana moves, chitta the mental force too moves. When prana is still, Chitta also still without any movement. By this steadiness of prana the Hatha Yogi reaches stableness and should thus control the Vayu air. (Chapter -2, Verse 2).
