Unity of Relative and Ultimate

On the ultimate level all events in samsara and nirvana never come into being, and so have no separate existence. On the relative plane they are illusory figments of mind, so again they have no separate existence. They are unoriginated events appearing in a plethora of magical illusion, which is like the reflection of the moon in water, possessing an inherent acausal dynamic. Since this essentially insubstantial magical illusion also never comes into being, ultimate and relative are identical and their identity is the one cause. Thus intuitive realization of [total presence] arises [with attainment of the unity of the two truths].
