The effect of Asana is to put an end to the dualities or the differentiation between body and mind, mind and soul...In that exalted position, the mind, which is at the root of dualistic perception, loses its identity and ceases to disturb (her). Unity is achieved between body and mind and mind and soul. There is no longer joy or sorrow, heat or cold, honor or dishonor, pain or pleasure.”

— BKS Iyengar, from commentary on Patanjali's Yoga Sutras II.48 tatah dvandvah anabhighatah

From then on, the seeker is undisturbed by dualities.
