Mahabharata Udyoga Parva Chapter 34:3

Mahabharata Udyoga Parva Chapter 34:3 It is not easy to hold a long conversation uttering words full of meaning and delightful to the hearers. Well-spoken speech is productive of many beneficial results; and ill-spoken speech, O king, is the cause of evils. A forest pierced by arrows, or cut down by hatchets may again grow, but one's heart wounded and censured by ill-spoken words never recovereth. Weapons, such as arrows, bullets, and bearded darts, can be easily extracted from the body, but a wordy dagger plunged deep into the heart is incapable of being taken out. Wordy arrows are shot from the mouth; smitten by them one grieveth day and night. A learned man should not discharge such arrows, for do they not touch the very vitals of others. He, to whom the gods ordain defeat, hath his senses taken away, and it is for this that he stoopeth to ignoble deeds. When the intellect becometh dim and destruction is nigh, wrong, looking like right, firmly sticketh to the heart. Thou dost not clearly see it, O bull of the Bharata race, that clouded intellect hath now possessed thy sons in consequence of their hostility to the Pandavas. Endued with every auspicious mark and deserving to rule the three worlds, Yudhishthira is obedient to thy commands. Let him, O Dhritarashtra, rule the earth, to the exclusion of all thy sons. Yudhishthira is the foremost of all thy heirs. Endued with energy and wisdom, and acquainted with the truths of religion and profit, Yudhishthira, that foremost of righteous men, hath, O king of kings, suffered much misery out of kindness and sympathy, in order to preserve thy reputation.'
