Similarly, the difficulty is all about purifying the mental behaviour, which is spoiled by the delusions of the world; there is no need to set right the mental behaviour which is free from such delusions. Delusion-less behaviour is necessarily pure. It is without any trace of defect and doubt. Why should such be set right? Therefore, if men first control and conquer the external delusion, as much as possible, the internal tendencies will easily move in the direction of Atmananda. Yoga and Tapas is only another name for the path of the control and conquest of these external tendencies and delusions. The rules of Vaanaprastha are but methods to succeed in this Yoga or Tapas. When man subdues delusion of all types in the Vaanaprastha stage, the journey ends in Moksha. But, we cannot say that Moksha has only this one path. Through whatever path Grace is obtained that Path may be chosen. Liberation is achieved by these rules and observances of Vaanaprastha and it can be secured by following this Path. It also makes a man delusion-free. It gives him one-pointedness.
