The Seven Types of Two Truths

The seven types of two truths are as follows:

First, “real existence” is the mundane, “the extinction of real existence” is the real.

Second, “illusory existence” is the mundane, and “identifying this illusory existence as empty [of substantial Being]” is the real.

Third, “illusory existence” is the mundane, and “identifying illusory existence as both empty and non-empty” is the real.

Fourth, “illusory existence” is the mundane, and “the identity of illusory existence with emptiness and non-emptiness, that all dharmas are empty and non-empty,” is the real.

Fifth, “illusory existence and the identity of illusory existence with emptiness” is all called the mundane, and “neither existence nor emptiness” is the real.

Sixth, “illusory existence and the identity of illusory existence with emptiness” is all called the mundane, and “neither existence nor emptiness, that all reality is included in “neither existence nor emptiness,” is the real.

Seventh, “illusory existence and the identity of illusory existence with emptiness” is the mundane, and that “reality includes existence, includes emptiness, and includes neither existence nor emptiness,” is the real.
