All of the great Sages since the beginning of time have taught basically three direct methods for self-realization.
These three methods I'm going to share the highest teachings on earth.
If you only practice these things you would need nothing else and
we will awaken and become free which we already are anyway but
you don't believe it. It behooves us to practice these three methods.

The "first" principle is being in the acquaintance of Sages in satsang.
This is the highest teaching you can get.

The "second" direct method is self-inquiry.
Self-inquiry is very important also.
But Bhagvan Sri Ramana Maharshi and other great Sages, Shankara, many Sages, manySaints, have emphasized the importance of
self-inquiry, atma-vichara. It's very easy to do.
You should practice all day and all night.
Especially if you've found a Sage

The "third" direct method is self surrender.
You can do all three of these things simultaneously you know.
You can be with a Sage, practice self-inquiry and also surrender.
This is what a true devotee does. They do all three.
Without even knowing that they're doing them.
