Why did Bhishma Ashtami take a vow of celibacy?

Bhishma had the boon of Ichha Mrityu, meaning he could choose the time of his death. When he was struck down by Arjuna arrows, he lay on a bed of arrows, waiting for the right moment to leave his body. According to Hindu tradition, departing during Uttarayana is considered highly auspicious. Visit us for more information.
