Ultimate heart essence transcends all imagination and expression.
The decisive experience of ineffability is the ultimate heart essence.
Since all phenomena of the world of appearances and possibilities, whether of samsara or nirvana, are ineffable by nature, they are beyond existence.
Since the way in which they manifest is unceasing, they are beyond nonexistence.
Since they are neither existent nor nonexistent, they are beyond being both.
Since there is no such duality, they are beyond being neither.
Since they neither “are” nor “are not,” the ultimate heart essence cannot he characterized as some “thing,” for it transcends all imagination and expression.
