All unhappiness is due to the ego. With it comes all your trouble. If you would deny the ego and scorch it by ignoring it you would be free.
Ramana MaharshiIf a man considers that he is born, he cannot avoid the fear of death. Let him find out if he has been born or if the Self has any birth. He will discover that the Self always exists, that the body that is born resolves itself into thought and that the emergence of thought is the root of all mischief. Find from where thoughts emerge. Then you will be able to abide in the ever-present inmost Self and be free from the idea of birth or the fear of death.
Ramana MaharshiEating, bathing, going to the toilet, talking, thinking, and many other activities related to the body are all work. How is it that the performance of one particular act is alone (considered) work? To be still is to be always engaged in work. To be silent is to be always talking.
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.
Ramana MaharshiIn accordance with the prarabdha of each, the One whose function it is to ordain makes each to act. What will not happen will never happen, whatever effort one may put forth. And what will happen will not fail to happen, however much one may seek to prevent it. This is certain. The part of wisdom therefore is to stay quiet.
