The Dharmakaya. The Truth Body.

[KevinSolway]

The simplest way to explain Dharmadhātu is that it is all of Reality, but conceived as all its elements (as a single category) rather than as a whole.

For example, a cake might be the "body" (kaya) but the slices are the elements (dhātu).

In the case of the Dharmakaya (the Truth-Body, the All) then the elements would be things like matter, phenomena, concepts, etc, and are therefore, together, called Dharmadhātu (Truth-element)

All the slices of the cake are absolutely identical to the cake, but are given a different name, because they are conceived as slices rather than as a cake.

Tu-shun splits the Dharmadhātu, which is a single category, up into its various constituent elements.

Or you can go with what the Buddha said, and ignore imposters.

Hmmm... Interesting, but overly complicated, unnecessarily so. Well that's just my opinion. Thank you for bringing it to our notice.
