The Buddha's Instructions on Satyapatana

Vapina is the contemplation of Vadma or pleasantness, neutrality. The third aggregate is Sanya which means perception in Pali. We can apply this to every object and hear applied to the aggregates. See everything with perfect wisdom. This is not mine. I am not myself. So that becomes, it's like a mantra of liberation. If we just recognize the sound for what it is, there's no reactivity in the mind.
