The more your meditation goes deep, the less and less you will feel the burden of the mind. The more and more meditation goes deep, the less and less you will be a mind. Thoughts will become rare, and ultimately they cease. That doesn't mean you become unthinking; it only means that your consciousness becomes clear, transparent, without thoughts moving continuously as clouds. Whenever you need to think you can think; but now thought becomes an instrument to you, not an obsession as it is presently. Thoughts are an obsession without meditation.
