Just know what is happening in your mind - not happy or sad about it, not attached. If you suffer see it, know it, and be empty. It's like a letter - you have to open it before you can know what's in it.
If you use your mind to study reality, you won't understand either your mind or reality. If you study reality without using your mind, you'll understand both.

Live for an ideal, and that one ideal alone. Let it be so great, so strong, that there may be nothing else left in the mind; no place for anything else, no time for anything else.
As a rule, the mind, residing in a body that has become weakened by pampering, is also weak, and where there is no strength of mind there can be no strength of soul.
