Emptying the mind
You must not think that when there is nothing in your mind, you will become a fool or act like an idiot. This is not true. If you can keep your mind calm and quiet for ten or fifteen minutes, a new world will dawn within you. This is the root of all spiritual progress. Right now you can make your mind calm and quiet for only a few seconds, or for a minute, but if you can maintain your calmness, poise and tranquillity for half an hour or even for fifteen minutes, I assure you that inside your tranquillity a new world with tremendous divine light and power will grow.
When you do not have any thought in your mind, please do not feel that you are totally lost. On the contrary, feel that something divine is being prepared in your pure and aspiring nature. You cannot expect immediate results. The farmer sows the seed and then he waits; he never expects the crop to spring forth all at once. It takes a few weeks or a few months to germinate. Your mind can be like a fertile field. If you plant the seed of silence and poise and cultivate it patiently, sooner or later you are bound to reap the bumper crop of illumination.
The mind is not necessary for meditation, because thinking and meditating are absolutely different things. When we meditate, we do not think at all. The aim of meditation is to free ourselves from all thought. Thought is like a dot on a blackboard. Whether it is good or bad, it is there. Only if there is no thought whatsoever can we grow into the highest reality. Even in profound meditation thoughts can come in, but not in the highest, deepest meditation. In the highest meditation, there will be only light.
Slowly and steadily if you can still your restless mind, immediately and cheerfully God will open His measureless Heart.
