Thanks all for the responses. I'll answer questions as best I can:
Aman -- The retreat was with Reggie Ray's Dharma Ocean community in Crestone, CO. The "utterly mind-blowing" bliss didn't have an orgasmic feeling. It was much more on par with MDMA, times a thousand. Just a full-bodied bliss wherein the full-body might not be the best description as it was rather not contained by the bodily shell, so to speak.
Thom -- Thanks for pointing me towards those resources. I will definitely check them out.
"Remember, the point of direct pointing is to recognize the nature of present experience, and is not about a particular state. Trying to get back somewhere, or to get anywhere at all is a type of contrivance or fabrication that will prevent the types of realization that this practice aims to cultivate."
Thanks for this. I've only read about direct pointing and had no real idea of what it actually entailed.
Thom W:
You seem to be taking the energetic and dakini experiences lightly, which is good. Take especially lightly any seeming confirmations of "you" having "attained" things, especially when you have had such goals in mind. These realms are tricksy and fickle, as are many beings you may meet on the way. It is passing scenery, albeit wondrous and at times ecstatic.
If the experiences aid conviction in awakening and the path you are on, take them and use them as inspiration, let them boost your wonder and appreciation at just how utterly indescribably rich, nuanced and mysterious this ever changing moment is. Just be aware of the tendency to use said experiences to reify or solidify a "self" in relation to said experiences. The investigation / appreciation / knowing of what is in this moment arising has always been the path, is now the path, and always will be.*
Thanks also for this. In doing further research on whatever might be going on, what I am experiencing definitely fits the bill of the descriptions I've read of "kundalini awakening." Different traditions seem to treat this differently -- In Therevadin/MCTB terms, it mainly seems to be relegated to the area of A&P side effect. In Siddha Yoga/Kashmir Shaivism, it seems to be seen in terms of a necessary propellant to true awakening. And in the Tibetan forms I'm most familiar with, it's hardly mentioned (unless it does have something to do with essential nature of mind, something I'll look into further). Many parties mention that it can indeed make one crazy. Good fun!
..In any event, I'm not hitching my wagon to any of these things. Just, like you said, investigatin' and appreciatin'.
