The ego's phenomenal existence is transcended when you dive into the source from where the `I'-thought rises

To ask the mind to kill itself is like making the thief the policeman. He will go with you and pretend to catch the thief, but nothing will be gained. So you must turn inward and see where the mind rises from, and then it will cease to exist.

By constantly keep one's attention on the Source, the ego is dissolved in that Source like a salt-doll in the sea.

All that is required to realise the Self is to “Be Still.

There is no reaching the Self. If Self were to be reached, it would mean that the Self is not here and now but that it is yet to be obtained. What is got afresh will also be lost. So it will be impermanent. What is not permanent is not worth striving for. So I say the Self is not reached. You are the Self; you are already That.

Even in intake, the one steadfast thought is said to be the natural state. Nirvikalpa Samadhi will result when the sensory objects are not present.

Reality is simply the loss of ego. Destroy the ego by seeking its identity. Because the ego is no entity it will automatically vanish and reality will shine forth by itself.
