Q: How can I control the mind? 

M: The mind is intangible. In fact, it does not exist. The surest way is to seek it, then its activities will cease. 

Seek the mind. On being sought, it will disappear. The mind is only a bundle of thoughts. The thoughts arise because there is a thinker. The thinker is the ego. The ego, if sought, will vanish automatically. The ego and the mind are the same. The ego is the root-thought from which all other thoughts arise. Dive within. You are now aware that the mind rises from within. So sink within and seek. You need not eliminate the wrong "I." How can "I" eliminate itself? All that you need do is to find its origin and abide there. That is as far as your efforts can extend. Then the Beyond will take care of itself. You are helpless there; no effort can reveal it.
