Life has to be an incessant process of repair and reconstruction, of discarding evil and developing goodness. Paddy grains have to discard the husk in order to become consumable rice. Cotton has to be reformed as yarn to become wearable cloth. Gold nuggets have to undergo the crucible and get rid of alloys. Man, too, must purify his instincts, impulses, passions, emotions and desires so that he can progress by good thought, words and deeds. The individual is valued only on the basis of the level of transformation he has attained. (LDL, p. 81)
