Sambhogakaya existence

"Sambhogakaya existence is similar in some ways to the mode of existence of numbers.

Numbers are neither physically real, nor fictional. They have no location, no substance, no mass. Yet their meaning is undeniable. The sambhogakaya is like that.

Numbers are neither a human creation, nor separately existent. Numbers cannot be invented or manufactured. Yet without humans to know them, they would not appear. The sambhogakaya is like that."
