Directly transcending expedients, meditating intensely, as soon as we get the essence, then the esoteric and exoteric teachings of the Buddhas all appear at once. Then we ram through a number of barriers, then come back and read scriptures and treatises, which now seem like we've expounded them ourselves. Afterward we raze the forest of wisdom, kick over the site of enlightenment, destroy the transcendental, and cut off the pulse of the Buddhas and Patriarchs. Exoteric and esoteric -- what are these? Even the reality body and the wisdom body still have to withdraw from the universe!
