The mind can assert anything and pretend it has proved it. My beliefs I test on my body, on my intuitional consciousness, and when I get a response there, then I accept.
Are you acquainted with the mood of mind in which, if you were seated alone, and the cat licking its kitten on the rug before you, you would watch the operation so intently that puss's neglect of one ear would put you seriously out of temper?
When your mind doesn't stir inside, the world doesn't arise outside. When the world and the mind are both transparent, this is true vision. And such understanding is true understanding.

I am slow to learn and slow to forget that which I have learned. My mind is like a piece of steel, very hard to scratch any thing on it and almost impossible after you get it there to rub it out.
As long as the mind is seeking to fill itself, it will always be empty. When the mind is no longer concerned with filling its own emptiness, then only does that emptiness cease to be.
