... you must concentrate totally upon the awareness of ‘you’, without thought of any kind, or (alternatively) try to catch the ‘I-thought’ as it rises from within and then hold on to that firmly to the exclusion of all else.

The Eternal Light
Believe nothing because a wise man said it;
Believe nothing because it is generally held;
Believe nothing because it is written;
Believe nothing because it is said to be divine;
Believe nothing because somebody else believes it;
Believe only what you yourself judge to be true
- Gautam Buddha
