One should not think, as is ordinarily done, that there exists an abiding motionless substance at the center, around which its qualities exist, moving and changing. If you suppose noumenon to be such an abiding substance, you will be misled altogether. Even the Mahayanistic people who maintain the doctrine of two truths—the worldly or popular truth and the higher truth—are often mistaken by a dichotomic idea of argument. The Tendai School, therefore, sets forth the threefold truth; i.e., the truth of void, the truth of temporariness and the truth of mean. All things have no reality and, therefore, are void. But they have temporary existence. They are at the same time mean or middle, that is, true state, Thusness.

According to the school the three truths are three in one, one in three. The principle is one but the method of explanation is threefold. Each one of the three has the value of all. Therefore, when our argument is based on the void, we deny the existence of both the temporary and the middle, since we consider the void as transcending all. Thus, the three will all be void. The same will be the case when we argue by means of the temporary truth or the middle truth. Therefore, when one is void, all will be void; when one is temporary, all will be temporary; when one is middle, all will be middle. They are otherwise called the identical void, identical temporary and identical middle. It is also said to be the perfectly harmonious triple truth or the absolute triple truth.

We should not consider the three truths as separate because the three penetrate one another and are found perfectly harnlonized and united together. A thing is void but is also temporarily existent. It is temporary because it is void, and the fact that everything is void and at the same time tetnporary is the middle truth,
