Tirukkural 411: Heaing Knowledge

Wealth (gained) by the ear is wealth of wealth; that wealth is the chief of all wealth.

The stronger you are in your nature, the more you can bring through your real nature; the more you can enjoy the bliss of your true being. It is well worth working for. It is well worth craving for.
