The via positiva in mysticism is called the cataphatic:

Cataphatic -- Derivation: Gr kata, down + phanai, say, assert Definition: in the mystical tradition, the way of "affirmation": associating with God terms about which we have solid understanding in our this-worldly experience, terms we apply first to this-worldly things, but whose signifying core we attribute to God as well; an analogical naming of God. The "positive" way, the via positiva.

This is basically saying "God is this..." and "God is this..."
