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 Maharshi...Bliss is not something to be got. On the other hand you are always Bliss. This desire [for Bliss] is born of the sense of incompleteness. To whom is this sense of incompleteness? Enquire. In deep sleep you were blissful. Now you are not so. What has interposed between that Bliss and this non-bliss? It is the ego. Seek its source and find you are Bliss.
Ramana MaharshiThe activity affected by causes like fainting, sleep, excessive joy, grief, possession by spirits, fear etc goes to the heart, its own place.
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.
