Mental, vital, physical forms and structures withdrawn from the body leaving the higher evolved essence in the body is YOGA .
Social blindness is unable to see the social opportunities for a higher psychological effort.
Psychological blindness is inability to see or understand or comprehend the shortcomings which we enjoy now . Spiritually, one will be blind as long as he is awake either psychologically or socially . In a higher sense all are the same or similar. When a work stalls for a long time and prayer too does not move, analyse that work comparing it with another successful work on attitude, skills, alertness, values, etc and you will quickly spot out the obstacle or the missing link . The opposites meeting, instead of receding, produces a result in practical life .
