 Kaji is realized as one becomes aware of one’s self and activity as the micro-cosmic manifestation of the macro-cosmic activity and mystery of the cosmos itself. One could then also say that kaji expresses the mutuality and coherence or co-responding that obtains between the two major concepts characterizing esoteric Buddhism for Kūkai: hosshin seppō and sokushinjōbutsu, as two ways of conceiving from different angles the same interrelationality of the cosmos in its mantric and mandalic expressions. That is to say, in the mantric and mandalic nature of this interrelationality, the Buddha’s hosshin seppō on the one hand descends from the summit and spreads-out from the center, and the practitioner’s sokushinjōbutsu on the other hand raises him from below and gravitates him to the center. Their simultaneity means their non-duality as different aspects of the same dynamism of a cosmic emptiness. To realize this, is to affirm one’s own original enlightenment in one’s present body in simultaneous reception of Dainichi’s expounding of the Dharma.
