“One may be indifferent to the enjoyments of this world only in expectation of better enjoyments in the next. This kind of indifference is tainted with desires which bar the door to Knowledge. But the indifference that results from a due deliberation on the evanescent nature of this world as well as the world to come, is alone pure, and productive of the higher good.”

Adi Shankara, 8th century CE Hindu philosopher
