The reason that the four kayas become a great protection is that we begin to realize the way our mind functions, our state of being. We realize that whatever comes up in our mind is always subject to that flow, that particular case history, that nature. Sudden pain, sudden anger, sudden aggression, sudden passion - whatever might arise always follows the same procedure, so to speak, the same process

[This] is the best protection because it cuts through the solidity of your beliefs... All of those schemes and thoughts and ideas are empty! If you look behind their backs it is like looking at a mask... if you look behind it, it doesn't look like a face anymore, it is just junk with holes in it. You realize that you are ... not any of your big ideas. That is the best protection for cutting confusion.
