Meditation applies the brakes to the mind.

Calmness is the criterion of spiritual progress. Plunge the purified mind into the Heart. Then the work is over.

There 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.

Once the current of awareness of the self is set afoot, it becomes everlasting and continuous by intensification.

I see only what you see, but I notice what I see.

Call it by any name, God, Self, the Heart, or the Seat of Consciousness, it is all the same.

Concentration is not thinking of one thing. On the contrary, it is excluding all thoughts, since all thoughts obstruct the sense of one's true being. All efforts are to be directed simply to removing the veil of ignorance. Concentrating the mind solely on the Self will lead to happiness or bliss. Drawing in the thoughts, restraining them and preventing them from straying outwards is called detachment (vairagya). Fixing them in the Self is spiritual practice (sadhana). Concentrating on the heart is the same as concentrating on the Self. Heart is another name for Self.
