We think whatever we do the outcome is in our hands and sameway in spiritual enlightenment also, it is in our hands . But the fact is it is beyond human efforts
A saathak can do saathanaaas practices , but he cant decide when it has to yield results and fix time frame for it , but on the contrary, it is grace that decides when to start giving results and when to give you the final triple deathless body ( TDB ) and make him enter into chirrambalam
It all depends upon the maturity of the saathak and practices and the level of grace he has earned
In reality it can take several births to complete this mammoth journey of deathless life and TDB
