Meditation is a deliberate attempt to pierce into the higher states of consciousness and finally go beyond it. The art of meditation is the art of shifting the focus of attention to ever subtler levels, without losing one's grip on the levels left behind. In a way it is like having death under control.
One begins with the lowest levels: social circumstances, customs and habits; physical surroundings, the posture and the breathing of the body, the senses, their sensations and perceptions; the mind, its thoughts and feelings; until the entire mechanism of personality is grasped and firmly held.
The final stage of meditation is reached when the sense of identity goes beyond the 'I-am-so-and-so', beyond 'so-I-am', beyond 'I-am-the-witness-only', beyond 'there-is', beyond all ideas into the impersonally personal pure being.
But you must be energetic when you take to meditation. It is definitely not a part-time occupation. Limit your interests and activities to what is needed for you and your dependents' barest needs. Save all your energies and time for breaking the wall your mind had built around you. Believe me, you will not regret.
At the end of your meditation all is known directly, no proofs whatsoever are required. Just as every drop of the ocean carries the taste of the ocean, so does every moment carry the taste of eternity. Definitions and descriptions have their place as useful incentives for further search, but you must go beyond them into what is undefinable and indescribable, except in negative terms.
After all, even universality and eternity are mere concepts, the opposites of being place and time-bound. Reality is not a concept, nor the manifestation of a concept. It has nothing to do with concepts. Concern yourself with your mind, remove its distortions and impurities.
Once you had the taste of your own self, you will find it everywhere and at all times. Therefore, it is so important that you should come to it. Once you know it, you will never lose it.
But you must give yourself the opportunity through intensive, even arduous meditation. Give your heart and mind to brooding over the 'I am', what is it, how is it, what is its source, its life, its meaning. It is very much like digging a well. You reject all that is not water, till you reach the life-giving spring.
