法界次第初門 2.83

2.83

As for cultivating the divine eye: if, in deep dhyāna attainment, pure derived form of the four great elements of the form realm arises and abides in the eye faculty, one can then see sentient beings in the six destinies dying here and being born there, as well as see all the various shapes and forms in the world. This is the divine eye superknowledge.
