Tiruvalluvar

“ Whatever is not conferred by fate cannot be preserved although it be guarded with most painful care; and that, which fate has made his, cannot be lost, although one should even take it and throw it away. ”

“ The fate that loss ordains makes wise men's wisdom foolishness;
The fate that gain bestows with ampler powers will wisdom bless.
An adverse fate produces folly, and a prosperous fate produces enlarged knowledge. ”
