„He will be a man with strength of a myriad elephants, a great and royal rsi, of great fortune, great power, and great intelligence. And 100 powerful sons will be his, but because of his mother’s lack of virtue, he shall be born blind.“
Sources, Seer of the Fifth Veda: Kr̥ṣṇa Dvaipāyana Vyāsa in the Mahābhārata, Vyasa’s curse to the first widowed wife of his half brother on the son to be born to them. His mother [Satyavati] had asked him to produce heirs to the throne with the two widows of his half-brother. The first princess closed her eyes as Vyasa was in fearful ascetic condition when he slept with her. In due time Dhritarshtra was born blind. Quoted in p. 58.
