Hence all these four stages are necessary even as all the stages in the process of education are necessary. A Sannyasin can live anywhere except in his own house or even in the vicinity of his house. The more distant the place of living, the better. Nowhere is it suggested that a Sannyasin should lead a life of indulgent comfort, but he should be provided with the necessities required for helping others spiritually and to maintain his creature comforts. Grihasthas do not give donation foolishly, because they know the value of the donation which will benefit them also.
Necessary facility is different from unnecessary comfort.
The benefit which the householder donor receives by taking care of a Sannyasin cannot be regarded as a barter system. No Grishtha is under compulsion to give a donation because donations are made out of voluntary freewill. Unnecessary donations are unthinkable. Every householder knows what is good for him and he has intelligence enough to understand what he does. No Sannyasi is expected to demand donation from anyone, because it should come from the donor voluntarily and of his own accord.
