You can change your prarabdha through a simple, strong will or sankalpa.
The strength of the sankalpa can cause a rebirth in you in this birth itself. The next birth can happen now itself.
For example, people, especially householder disciples who feel they are caught up in their responsibilities ask me, ‘Swamiji, please bless me that I should be with you at least in my next birth.’ There are so many examples where they have been able to come and live in the adheenam just a few months later. It is just the strength of the will.
