The fact is that the mind is only a bundle of thoughts. The mind is fattened by new thoughts rising up. Therefore it is foolish to attempt to kill the mind by means of the mind. The only way of doing it is to find its source and hold on to it. The mind will then fade away of its own accord.
God dwells in you, as you, and you don't have to 'do' anything to be God-realized or Self-realized, it is already your true and natural state. Just drop all seeking, turn your attention inward, and sacrifice your ego mind to the One Self radiating in the Heart of your very being. For this to be your own presently lived experience, Self-Inquiry Meditation is a direct and immediate way.
