In true meditation the emphasis is on being awareness; not on being aware of objects, but on resting as primordial awareness itself. Primordial awareness is the source in which all objects arise and subside. As you gently relax into awareness, into listening, the mind's compulsive contraction around objects will fade. Awareness naturally returns to its non-state of absolute unmanifest potential, the silent abyss beyond all knowing.
Make your meditation a continuous state of mind. A great worship is going on all the time, so nothing should be neglected or excluded from your constant meditative awareness.
Walk, but make walking a meditation; walk knowingly Breathe, but let your breathing become a constant meditation; breathe knowingly. The breath going in: watch it. The breath going out: watch it. Eat, but eat with full awareness. Take a bite, chew it, but go on watching. Let the watcher be there in every moment, whatsoever you are doing.
Brahman is beyond mind and speech, beyond concentration and meditation, beyond the knower, the known and knowledge, beyond even the conception of the real and unreal. In short, It is beyond all relativity.
If you were only to listen, it becomes meditation. Without meditation you cannot hear. What is the meaning of meditation? Meditation exists only where mind is not; where the internal dialogue is gone.
