We read, we try to understand, we explain, we try to know. But a single minute of true experience teaches us more than millions of words and hundreds of explanations.
So the first question is: How to have the experience?
To go within yourself, that is the first step.
And then, once you have succeeded in going within yourself deeply enough to feel the reality of that which is within, to widen yourself progressively, systematically, to become as vast as the universe and lose the sense of limitation.
These are the first two preparatory movements.
And these two things must be done in the greatest possible calm, peace and tranquillity. This peace, this tranquillity brings about silence in the mind and stillness in the vital.
This effort, this attempt must be renewed very regularly, persistently. And after a certain lapse of time, which may be longer or shorter, you begin to perceive a reality that is different from the reality perceived in the ordinary, external consciousness.
