If the mind falls asleep, awaken it. Then if it starts wandering, make it quiet. If you reach the state where there is neither sleep nor movement of mind, stay still in that, the natural (real) state.
Ramana MaharshiIf you go the way of your thoughts you will be carried away by them and you will find yourself in an endless maze.
Ramana MaharshiGod illumines the mind and shines within it. One cannot know God by means of the mind. One can but turn the mind inwards and merge it in God.
Ramana MaharshiThere is no mind to control if you realise the self. The mind having vanished, the self shines forth. In the realised man, the mind may be active or inactive, the self remains for him.
