Bhishma had been given a boon few warriors in any epic receive: he would die only when he himself chose to. His father Shantanu granted it in gratitude for the vow Bhishma made as a young man – renouncing marriage, children, and any claim to the throne, so that Shantanu could marry the fisherwoman Satyavati without her own father’s fear that Bhishma’s descendants would one day contest her children’s inheritance. It was an oath so severe, so total, that the gods themselves reportedly rained flowers at hearing it and gave him the name Bhishma – “the terrible vow.” The boon of choosing his own death was Shantanu’s answer to a son who had just given up everything else a life could contain.
The fall that wasn’t a death
On the tenth day of the Kurukshetra war, Bhishma – by then the Kaurava army’s commander, still fighting despite loving the Pandavas more than the side he’d been born to serve – was brought down by Arjuna, who fired from behind the cover of Shikhandi, a warrior Bhishma refused to fight directly because Shikhandi had been born a woman in a previous life and Bhishma had sworn, decades earlier, never to raise weapons against a woman. Arrow after arrow struck him until, by the epic’s own description, there was no space left on his body wide enough to hold another – and he fell, at last, not to the ground, but onto a bed made entirely of the arrows already lodged inside him, suspended above the earth by his own wounds.
He did not die. He could not, until he chose to, and he had reasons of his own not to choose it yet.
Fifty-eight days of waiting
Bhishma waited specifically for the sun to begin its northward journey – Uttarayana – a period considered astrologically and spiritually more auspicious for departing the body, according to the beliefs he held. That wait lasted fifty-eight more days, through the remainder of the war, through Duryodhana’s death, through the aftermath and the mourning, with Bhishma still lying on his bed of arrows the entire time, fully conscious, fully present, holding court from the position his own body had become.
It is during these fifty-eight days that Bhishma delivers some of the Mahabharata’s most extensive teachings on dharma, statecraft, and duty, directly to Yudhishthira, who comes to him not in triumph but in grief and guilt, needing guidance on how to rule a kingdom he won through a war that killed the very grand-uncle now teaching him how to be a just king. Bhishma, dying by his own arrows for two months, spends that time preparing the person who helped defeat him to govern well – not out of contradiction, but because his loyalty to the throne of Hastinapura had always mattered more to him than which specific occupant sat on it.
Choosing the moment
When Uttarayana finally arrived, Bhishma released himself, choosing his own death exactly as the boon had always promised – not forced from life by any warrior’s arrow, despite the hundreds lodged in his body, but departing only once he had decided the moment was right, and only after using the extra time the war had accidentally given him to make sure something useful came out of a death this long and this strange.
