My very dear one,
What came out best for your three-year retreat is Vajrayogini. It comes out for you to start after two years, but you need to do preliminary practices before that, if you haven’t done them already.
Generally there are nine preliminaries before the retreat. If you have done any of them in the past, that can be counted. So please let me know.
Thank you very, very much, a billion times, that you kept my advice and got done whatever you have done. Great!
With much love and prayers...
