~My mind is on fire
To understand this most intricate riddle ~~ (Confessions of St Augustine)

Practicing Iyengar Yoga for twenty years --the fascination & interest in the subject continues to grow. 
Intricacies of action within the practice of the postures keep the mind engaged in the NOW. This is how Yoga happens. The pose is the vehicle to Yoga. “Yoga is the vehicle to heaven” (heaven=union/ transcendence of duality/ going beyond identification with impermanent states of nature to experience Oneness)
