So I am NOT saying that you are NOT to use your mind, but don't be USED by the mind.
Right now the mind is the master and you are only a slave.
Meditation makes you a master and the mind becomes a slave. And remember: the mind as a master is dangerous because, after all, it is a machine; but the mind as a slave is tremendously significant, useful. A machine should function as a machine, not as a master. Our priorities are all upside-down — your CONSCIOUSNESS should be the master.
So whenever you want to use it, in the East or in the West — of course you will need it in the marketplace — USE it! But when you don't need it, when you are resting at home by the side of your swimming-pool or in your garden, there is no need. Put it aside. Forget all about it! Then just be.
And the same is the case with the ego. Don't be identified with it, that's all.
