If you understand the two truths and wish now to experience the apparent Truth of Non-Existence and generate the liberating melding with the apparent Truth of Existence then you must move to a meditation that allows its absorption.
Now another way of describing this melding is to experience the rising of the experience of EXISTENCE and experience the mind-moments before the generation of the "name and form" that makes apparent existence possible.
This means that in a meditative experience one must absorb the "experience" that the EXPERIENCE is generated from the mind and then see its rising as apparent EXISTENCE, its continuation and its falling away, only to absorb another rising and falling away.
Now you must be sure that you fully understand this.
Now I will present that in another way.
One must in the absorption meditation experience the rising, continuation and falling away of thoughts and absorb the experience that all arises from the mind.
Does this appear familiar?
It should.
