Pleasure forms poison for a poor man. War is poison for a coward. Scriptures and knowledge are poison for one who never studies and practices. Food is poison for one who cannot digest it.
Anger lasts for a second in noble men. It lasts for an hour or two in intermediate or ordinary men. In a mean-minded person it last for a whole day and night. In the vilest man it lasts till death.
Life without education and knowledge is waste, like the tail of a dog that is neither useful or conceal its private organs, nor useful in driving away disturbing flies.
