Of course, that aspect of the complete enjoyment body, the sambhogakaya, which arises from countless accumulations of merit over countless eons, teaches the Dharma, emptiness, directly to his disciples, whereby the disciples realize emptiness. Not only that, he teaches Dharma by way of blessings and emanations even through the four elements. For the disciples with pure karma, the sound of trees and so forth can be a direct teaching on emptiness, leading them to the direct realization of emptiness.
