Nanak! By speaking insipid words, the body and mind become insipid. -Guru Nanak Sahib, Guru Granth Sahib, 473
Message: A fool speaks to his ego, the wise question their ego
Gurbani advises us not to call any one bad, and not to argue with a fool.
The consequences of uttering harsh or insipid words are negative.
When we use rude language and utter impolite words, they affect our body and mind.
We lose our own peace of mind, lose our temper, and further hurt the feelings of others.
One who talks rudely loses his or her reputation and is not welcomed anywhere. No one wants to talk to him or her anymore. Such a person is avoided by others due to his or her foolishness.
The Guru has given us a valuable advice. We may choose to be polite and friendly or we may choose to be rude and rough. The choice is ours.
The music that can deepest reach, and cure all ill, is cordial speech. -Ralph Waldo Emerson, author and philosopher, 1803-1882
Etymology: From Sanskrit boll (speak) → Prakrit bollai (speaks).
