Part 3d.1 - Sambhogakaya: The brief teaching

Now as for the teaching of the fourth kaya, the spontaneously present sambhogakaya, as for the space-like dhatu of inner luminosity:

From this comes the self-experience of sambhogakaya,
Having the five perfections, those of time and place,
Along with those of teacher, Dharma, and retinue.

From within the space of inner luminosity, dharmata, comes the appearance of sambhogakaya possessing the five certainties, the external luminosity of self-appearance. The teachers are the regents, the principal ones of the five families. As empty form, these appearances of buddhahood are not the same as others. The palaces and so forth of these fields are established from the fundamental luminosity of self-experience. If such things are examined, none of their individuating characteristics exist.

The Stages of the Path of Miracle (sgyu ‘phrul lam rim) says:

The self-experience of self-perfected insight
Is fields, and palaces, with their thrones, and ornaments.
They make their appearance in many rays of light.
