That makes more sense now!
I suddenly realized something over the few days that I've been reading sutras and material from this forum/site and trying to apply them in my practice.
The "method" that got me to Jhana the other time (skeleton meditation, which was based off mindfulness of the body as Jhanananda had stated) had the same stages that Jhanon talked about in
this thread.
The first step of the method was to focus on "illuminating" the skeleton in the body by contemplating on the foulness of the flesh, organs and "discarding them away". The method was to contemplate the rotting and pus-forming on the flesh and skin, revealing the bone. I found that by doing this, in my mind I was in a way, letting go of the physical body. By just maintaining a balance in my attention, not exerting, yet still being mindful, the bone naturally illuminates. So I contemplated every part of the body, starting from my left big toe, then to all toes, then upwards, until I reached the skull. By the time I reached the skull, my attention seemed very sustained and there was a very intense tingling and blissful sensation throughout my body.
I did not even need to keep my attention steadfast on it any more, I took the advice from GWV to anchor my awareness on the blissfulness and joy.
Then the next step was usually to imagine even the bones turning to dust and scattering. I think this represented a form of letting go inside my mind. When I did this, the joy inside of me surged into that of an orgasm.
This was then followed by equanimity, where I could no longer feel any physical bliss. Instead, I started to feel a sort of "tingle" that didn't come from the physical body.
I experienced vivid dizziness, flashing lights, and a tinnitus-like sound that was growing in the background. I could have sworn I almost went into this strange pulling sensation as if my body was being sucked upwards into some kind of space. Then I just freaked out from the new experience and pulled back.
Could it be that I almost generated a mind-made body? It could also have been an anticipation because I've been reading literature and finally understanding that these "siddhis" as described by the sutta was not performed by the physical body but the mind-made body.
I then repeated the meditation in the same way and strangely... I consistently got back to the same point again and again. I guess I'll just keep coming back to face this irrational fear.
It's really amazing how much I've progressed since I've been to this forum/site. I hope I can one day reach the progress of the more advanced mystics here haha.
