The search "Who am I"...ends in the annihilation of the illusory "I" and the Self which remains over will be as clear as a gooseberry in the palm of one's hand.
Ramana MaharshiTurn your vision inward and then the whole world will be full of the Supreme Spirit.
Ramana MaharshiThe mind is only a bundle of thoughts. The thoughts have their root in the I-thought. Whoever investigates the True "I" enjoys the stillness of bliss.
Ramana MaharshiConcentration 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.
