This has five parts: (1) how one attains full awakening first, (2) the buddha bodies and their qualities, (3) the emanation body, (4) establishing the one vehicle, and (5) explaining the time of manifest awakening and abiding.
How one attains full awakening first
This has two parts: the actual point and rebutting the objections.
The actual point
Just as moonlight can shine bright in a cloudless night sky,
he strives again on the ground that gives rise to the ten powers,
and in Akaniṣṭha he will find the object of his striving, supreme peace,
which is unrivaled as the ultimate culmination of all qualities.
Just as, for example, moonlight in a cloudless sky can shine bright for all those traveling [at night], so too the one who has found that tenth ground of awakening mind, which clears away the darkness obstructing the attainment of the buddha’s qualities, knows that he can attain the qualities of the buddha by himself.
So he strives once again — that is, he initiates further efforts on that tenth ground, the very ground that will give rise to the buddha’s ground endowed with ten powers — so that he attains the buddha’s ground.
For example, there may be many different types of vessels, such as vases, bowls, and so on, but the space that exists within, or pervades, these different containers remains the same, in that space is the mere negation of obstruction.
Likewise, although differentiations of phenomena exist — such as form, feelings, and so on — created by causes and conditions, no such differentiations exist in terms of their suchness, their absence of arising through an intrinsic nature.
Thus one should recognize that the ultimate realities of all things share the same or a single taste.
