After having stopped the lower activities of the mind, it must be made receptive; and, instead of weaving all kinds of empty and idle thoughts, the mind should receive intuitions from above.
Find out for yourself what are the possesions and ideals that you do not desire. By knowing what you do not want, by elimination, you will unburden the mind, and only then will it understand the essential which is ever there.
It is easy to remove the mind from harping on the lost illusion of immortality. The disciplined intellect fears nothing and craves no sugar-plum at the day's end, but is content to accept life and serve society as best it may. Personally I would not care for immortality in the least. There is nothing better than oblivion, since in oblivion there is no wish unfulfilled. We had it before we were born, yet did not complain. Shall we whine because we know it will return? It is Elysium enough for me, at any rate.
