I wish all my indian friends and whoever who is celebrating a Happy Deepavali. I always associate Ganesh as a Hindu god. I discovered few months back that it's known as Ganapati in Tibetan Buddhist context. And I learnt that Ganesh, like many Hindu gods, had been taken up by the tantric Buddhist practitioners long ago. And I was given the Ganapati initiation by Paltrul Rinpoche too.
Om gam ganapati soha! *mantra of Ganapati*
