Whenever a thought arises, instead of trying even a little either to follow it up or to fulfil it, it would be better to first enquire, "To whom did this thought arise?"
Ramana MaharshiThe greatest obstacle to enlightenment is getting past your delusion that you are not already enlightened.
Ramana MaharshiTo 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.
