Can you fill in more context for the term remembrance?
Mainly that it has nothing to do with memory, everything to do with recognition.
Recognition of what?
Of Self beyond self.
What about its relative degrees?
The more there is, the more lacking it can seem, as the quality and degree seem limitless to our limited mind and to our longing heart, although at its core it remains unchanged.
And the prerequisites?
Prerequisite is awareness of one's actual self, embedded in the false self.
And then gravitating to the point of contact, the place of connection to the presence of the Beloved. At the very least, inviting that contact and connection to take place.
