Meditation has been laid stress upon by all religions. The meditative state of mind is declared by the Yogis to be the highest state in which the mind exists. When the mind is studying the external object, it gets identified with it, loses itself To use the simile of the old Indian philosopher: the soul of man is like a piece of crystal, but it takes the colour of whatever is near it. Whatever the soul touches … it has to take its colour. That is the difficulty. That constitutes the bondage. The colour is so strong, the crystal forgets itself and identifies itself with the colour. Suppose a red flower is near the crystal and the crystal takes the colour and forgets itself, thinks it is red. We have taken the colour of the body and have forgotten what we are. All our fears, all worries, anxieties, troubles, mistakes, weakness, evil, are from that one great blunder – that we are bodies.
The practice of meditation is pursued. The crystal knows what it is, takes its own colour. It is meditation that brings us nearer to truth than anything else. (IV 227)
