In Tsong-kha-pa’s The Essence of Eloquence ana-
lyzing the depiction in the Sūtra Unraveling the Thought of the Buddha’s response to Bodhisattva Paramārthasamudgata’s question regarding an apparent contradiction in Buddha’s sūtras. In this response the Buddha initially lays out the first of the three natures and three non-natures—that imputational natures are character-non-natures.

In this book Jeffrey Hopkins draws on his trilogy on the
section of the Mind-Only School titled Dynamic Responses to Dzong-ka-ba’s The Essence of Eloquence to identify these many meanings along with making references to detailed exposition of the issues especially in the third volume, Absorption In No External World: 170 Issues in Mind-Only Buddhism. Through these multiple identifications, we come to see that Tsong-kha-pa’s followers step into his shoes
by using his principles of organization to extend his thought further, such that they come to know his pivotal concepts in an active and creative way, rather than just repeating what
he said. Since the principles of his system are put to active use, these come to life in a way otherwise impossible. Examination of problems in debate and in literary composition becomes a method of profound internalization.
