For instance, a more advanced kind of Vajrayana meditative practice is called Dzogchen. This is a system in which one returns to one’s original state of being (hence human nature in its original form). This practice is known in Tibet.
Aside from the standard mantras, mudras, and mandalas of Vajrayana, in this practice one also particularly needs to visualize a Buddhist deity as a way of identifying with it (to become that deity).
As we saw in Chinese Mahayana, Dzogchen, too, teaches the Middle Path.
That means that it teaches that the universe is both empty and substantial at the same time. Because we understand that the universe is not only empty and not only as we see it, we thereby follow a middle path, recognizing them both as being included in the larger truth.
