happiness: an experience

How many times when we feel happy do we feel a sadness for the time when all this will go away and yearn for an unending stream of happiness? How many times when we feel sad do we long for a Joy/Bliss that never ends? The experience is best described by Ramana Maharshi in his famous forty verses: This is from the translation of Arthur Osborne:

31. For Him who is immersed in the bliss of the Self, arising from the extinction of the ego, what remains to be accomplished? He is not aware of anything (as) other than the Self. Who can apprehend his State?

or the translation by Alan Jacobs

31. Having extinguished the ego, the jnani has no other purpose in life but to remain immersed in the bliss of the Self. What remains to be done by him, who, having extinguished the ego, remains immersed in the bliss of the self? He is aware of nothing but the Self. Who can understand his state?

If Ramana has described it that way, can Shankara be behind? This is how The Master describes happiness in this prasna-uttara-malika:

53. Who lives in happiness?
He who has attained samadhi.

PS: had all these thoughts today. It was amazing.
