毗湿摩（梵文：भीष्म）在摩诃婆罗多中是花钏王和奇武王的同父异母兄长，福身王和恒河女神所生的第八个儿子。

毗湿摩原是天神，名叫「神光」，但在天界与七个天神合作，偷了极裕仙人的如意牛，被极裕诅咒成为凡人，这八个神去跪求极裕仙人，极裕原谅了他们，说他们转世之后，立刻会死，就可以回到天庭。不过「神光」因为是窃盗的领导人，必须在人世间逗留。八个神又找到恒河女神，希望女神下凡帮助他们。

福身王看到了一名来历不详的美女，美艳绝伦，于是向她求婚，美女说：「不可以探问我的来历，不可以干涉我的行为，我就委身于你。」福身王应允了。原来这美女即是恒河女神化身，福身与女神生了八个儿子，女神为了让这些天神能够重返天界，前七个一出生，就被女神丢到恒河里溺死，让他们的灵魂能够回到天界。但福身王并不知情，最后，终于受不了，不让女神杀死最后一个儿子，这个幸存的儿子便是毗湿摩。
