55. These dream-like experiences, all of them residing in the subtle transitional body (ātivāhikaśarīra), appear vividly at the consciousness (bodha) that emerges after death, manifesting as clear creations. Yet, they are visions of illusion that are themselves a different kind of delusion, falsely presented, just like the continuous flow of a mirage-river.
