In the Buddha's life story we see the three stages of practice: Morality comes first, then concentrated meditation, and then wisdom. And we see that the path takes time.
Meditation means the mind is turned back upon itself. The mind stops all the thought-waves and the world stops. Your consciousness expands. Every time you meditate you will keep your growth.
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.
Meditation, you know, comes by a process imagination. You go through all these processes purification of the elements - making the one melt the other, that into the next higher, that into mind, that into spirit, and then you are spirit.
