...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 MaharshiEven the structure of the atom has been found by the mind. Therefore the mind is subtler than the atom. That which is behind the mind, namely the individual soul, is subtler than the mind.
Ramana MaharshiEvery living being longs always to be happy, untainted by sorrow; and everyone has the greatest love for himself, which is solely due to the fact that happiness is his real nature. Hence, in order to realize that inherent and untainted happiness, which indeed he daily experiences when the mind is subdued in deep sleep, it is essential that he should know himself. For obtaining such knowledge the inquiry 'Who am I?' in quest of the Self is the best means.
