There are three golden mantras to great meditation:
For the 15-20 minutes in the day that you're meditating, remember these three mantras:
1. I want nothing: For the 15-20 minutes of meditation, let go of all desires – including the desire to let go of all desires! After 15-20 minutes, you can have all that you want.
2. I will do nothing: Do not get entangled with thoughts and emotions that run through you, just observe… as if you are sitting on a park bench and watching the children play.
3. I am nothing: If you think you’re somebody great, a fool, rich, or poor - you can’t meditate. If you think you are somebody great or somebody hopeless, there is no way you can settle down to the deepest core of the being.
