Even though I have given up this practice, I was highly impressed by this report. Bravo!   I am amazed how you were able to track kundalini and channel all the bursts with containment throughout the session.  It shows a high degree of containment of energies overall. 

I wondered about this statement of yours:

 My last posture rose kundalini up into the head forcefully, paralyzing the subtle body momentarily and leaving the core-self in complete silence.

In my meditation, I have encountered this complete silence of the psyche a few times.  I always thought it was the mind that is silenced, at which point the core is all alone to make unbiased notations and deductions.  Just wondering what you might think about that.

Again. Well done.  Seeing the buddhi organ even once, even briefly, is a breakthrough, clearing the way for further progress.
