जलमृणालन्यायः

It takes its origin from the growth of the stalk of a lotus with the increase of water in a tank during the rains. Again when the dry season comes and the surface of the water begins to sink, the stalk of the lotus gets dry but it does not die away. Similarly when a great man or nation by the freaks of fortune is reduced to miserable condition he does not lose thereby his usual nobleness of mind.
