Sri Ramana Maharshi

That which is Bliss is also the Self. Bliss and the Self are not distinct and separate but are one and the same. And That alone is real. In no single one of the countless objects of the mundane world is there anything that can be called happiness.

It is through sheer ignorance and unwisdom that we fancy that happiness is obtained from them. On the contrary, when the mind is externalized, it suffers pain and anguish. The truth is that every time our desires get fulfilled, the mind, turning to its source, experiences only that happiness which is natural to the Self.

Similarly in deep sleep, in spiritual trance (samadhi), when fainting, when a desired object is obtained, or when evil befalls an object considered undesirable, the mind turns inwards and enjoys that Bliss of Atman. Thus wandering astray, forsaking the Self, and returning to it again and again is the interminable and wearisome lot of the mind.

It is an unwise person who acts thus, whereas the wise man never leaves the shade: in the same way the mind of the Enlightened Sage (Jnani) never exists apart from Brahman, the Absolute. The mind of the ignorant, on the other hand, entering into the phenomenal world, suffers pain and anguish; and then, turning for a short while towards Brahman, it experiences happiness. Such is the mind of the ignorant.
