Here are a few of the gifts of states, of shifting contents of experience…
Over time, they invite us to recognize and realize impermanence… inherent in anything that comes is its going. Sadness, joy, oneness, bliss, suffering, a particular insight, different types of samadhi… they are all temporary visitors.
They also invite a noticing and differentiation of different areas of the terrain… in my own experience, I can see how different states has allowed me to discover and differentiate aspects of the terrain… the void (allowing identities to fall away), alive presence (soul level), endarkenment (feminine divine), luminous emptiness (masculine divine), the three centers (head, heart and belly, each one in the foreground at different times), oneness (a vague sense of an I one with God), suffering (being caught up on the inside of beliefs), and so on. Each of these are noticed, clarified and differentiated from the other ones by dipping into them through various states.
As Ken Wilber would point out, the states and what they reveal are interpreted through our psychograph… our lines of development and where they are at (their stages) and in particular through the conscious framework we operate from (cognitive line).
Some states offer their particular gifts. For instance, the state of unusual clarity and stability of attention invites us to inquire with more differentiation into what is… including the mechanisms of samsara.
Finally (?), they also offer glimpses of what is ahead on the path, and what we thought was behind us but wasn’t…! For instance, void temporarily wakes up to itself, and is then covered up by a sense of a separate self, which offer a new context to the path and our life… it offers a glimpse of how it is when all identifications are vaporized, and a direction for our continued practice. And dipping into being caught up in particular beliefs, and their accompanying drama and suffering, shows us that more work is required, we were not quite done with that one.
States are visitors which come on their own time, whether invited or not… and they can also be explored in a more systematic way through for instance the Big Mind process (filtered in a limited way through the head center).
