It's a mistake to expect benefits from any pose. Expectations make you restless because if you fail to get what you expect, you feel miserable. Yoga practice is an act of adoration to the Lord. You do it because it has to be done. If you have this mental attitude, your selfishness disappears and the benefits come.
With constant practice, one can improve his physical body and mental attitude rapidly, thereby igniting the higher motives of making one’s self useful to himself and all mankind.
Everything depends on your mental attitude.
It is my greatest joy to share with students this knowledge that I have acquired in the past 50 years of practice and study. Dharma Yoga practice will give one’s body the power and strength to have resistance to common illnesses and diseases. With proper encouragement and increased faith in the Guru, as one can improve his physical body and mental attitude rapidly, thereby igniting the higher motives of making one's self useful to himself and all mankind.
