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.
Perception without the word, which is without thought, is one of the strangest phenomena. Then the perception is much more acute, not only with the brain, but also with all the senses. Such perception is not the fragmentary perception of the intellect nor the affair of the emotions. It can be called a total perception, and it is part of meditation.
Just as I sit down to meditate, all the vilest subjects in the world come up. The whole thing is nauseating. Why should the mind think thoughts I do not want it to think? I am as it were a slave to the mind.
Everything is based on mind, is led by mind, is fashioned by mind. If you speak and act with a polluted mind, suffering will follow you, as the wheels of the oxcart follow the footsteps of the ox. Everything is based on mind, is led by mind, is fashioned by mind. If you speak and act with a pure mind, happiness will follow you, as a shadow clings to a form.
All human beings have an innate desire to overcome suffering, to find happiness. Training the mind to think differently, through meditation, is one important way to avoid suffering and be happy.
