After Vichitravirya’s death, his mother Satyavati sent for her first born, Rishi Veda Vyasa. She asked him to father children on the widowed queens of Vichitravirya according to the prevalent custom of Niyoga. Veda Vyasa had come from years of intense meditation and as a result, he looked tremendously unkempt. When he approached Ambika, she closed her eyes in fear. As a result the blind Dhritrashtra was born.
