Canakya Pandita said, ayusah ksana eko ‘pi na labhyah svarna-kotibhih… Svarna means gold coins, and koti means ten millions. So suppose today is 6th December. Now seven o’clock, morning, seven o’clock, 6th December, passed. Can you bring it again by paying one crores [ten million] of gold coins? Hm? That “Let me get back again seven o’clock, 6th December, 1975, again”? No. It is gone forever. So just see the value that you cannot get back even a moment of your life by paying millions and millions of dollars. How time is valuable, just calculate. Therefore Canakya Pandita [said], sa cet nirarthakam nitah ka no hanis tato ‘dhika. If you waste your time, such valuable time, for nothing, just imagine how much loser you are.
