2.151

[Treatise:] What realm is realized? [It is tathatā] ... it is called the dharmakāya. [Commentary:] This distinguishes the essence of realization. "What realm is realized? It is tathatā": this presents the Dharma that is realized. As for "because, relying on the evolving consciousness, it is taken as a realm," and so forth: this resolves an external doubt and objection. Since experiential integration has been called realization, within it there is no distinction between subject and object; why then is the ultimate spoken of as a realm? Because, relying on the evolving aspect simultaneous with realization-cognition, which is able to apprehend a realm, the ultimate is spoken of as an object. In order to show that although the bodhisattva realizes tathatā, it is not yet purely so, the evolving consciousness is provisionally spoken of. But in actual realization, experiential integration with tathatā leaves no distinction between principle and cognition; how could there be an objective realm? "Only the cognition of tathatā is called the dharmakāya": this concludes by clarifying that it is not an object. That is to say, the realizing bodhisattva is called the dharmakāya. The dharmakāya is solely suchness-pure cognition. Since between that principle and cognition there is no separate essence, it is therefore the realm of tathatā.
