“Lord Marpa, on the verge of passing into nirvana, transformed his consort Dagmema into a sphere of light and dissolved her into his heart center. Straightening his body, he said, “Sons, if you do Phowa, do it like this!” Then a sphere of five-coloured light the size of an egg ascended into the sky from a crack at the crown of his head.”
