Meditation is sticking to one thought. That single thought keeps away other thoughts; distraction of mind is a sign of its weakness; by constant meditation it gains strength.
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 MaharshiGod illumines the mind and shines within it. One cannot know God by means of the mind. One can but turn the mind inwards and merge it in God.
