Explanation

'Speak clearly' was about clarity; this is about patience and gentleness. A hasty word can never be taken back. Thiruvalluvar says, 'Whatever else you fail to guard, guard your tongue; if you do not, you will grieve over the faults of speech' (Kural 127).
'A wound burned by fire heals within; the scar burned by the tongue never heals' (Kural 129). Tradition holds that a single mocking remark by Draupadi deepened Duryodhana's enmity in the Mahabharata.
