Very interesting stuff, thanks for posting it. In my early years I drew down energies in the form of the Holy Spirit, or Holy Ghost, and Jesus, Mary etc. I experienced these very strongly as beautiful energies.
These often landed in the heart and then I could also allow emotions etc to ascent from the heart upwards and become transcended.
My issue with this as a stand alone process is that it seems to be possible to have blocks in the lower chakras whilst experiencing wonderful top energy descents and descents. In the West there seems to be a classical blockage around the middle of the body and this can take some unblocking.
It may explain the uncontrolled behavior of many priests and nuns and monks in their various sexual misconducts. Having a "high" spiritual life whilst being blocked down below, leading to addictive sexual behaviors.
Having said that, I would guess that energy rising in the form of kundalini can lead to just as much trouble with addictive behaviors relating to the "pleasures" associated with same.
In my experience, no matter what system one uses or happens upon the big important part that is an essential part of it is quality inquiry. Life is one long inquiry and what ever system one uses it needs quality inquiry to make it real.
One thing I noticed the heart is the most important thing to nourish. When the heart is weak, the energies in the body can become pretty chaotic. The heart harmonizes the energy flow.
