Vacuity, according to Tendai, means nothing but the non-being of a particular existence apart from the universal Dhammata. We speak of this or that thing or substance, quality or condition, and think it to be a reality, in and by itself. Nothing is more erroneous than this, because we know that nothing in this world, visible or tangible, exists without causal nexus. It is a Dhamma, a thing or condition, because it is a manifestation of the Dhamma, the law of causation. Vacuity does not mean the voidness of any existence in itself, but vanity of the view that sees in it a reality apart from the fundamental Dhammata.
