Tukaram, Poem 1076

Snub-nosed man is ashamed when he looks in a mirror; he is vexed to see his nose as it is. Thus, where bad qualities stand in the way, what is true seems hostile to us. What is a diamond to a blind man? It is just like a flint. Tuka says, A dog goes on barking, because he does not know the right time to bark.
