I just want to say that I appreciate the questions asked and the answers in this thread, and they aspire me to practice more diligently.
Good to hear from you again, bodhimind. I am glad that the dialog here is giving you some inspiration to practice more intensely, and providing you guidance.
I wish to ask more about the various planes of existence during an OOBE. I remember Jhanananda mentioned 5th jhana as post transition through kasina into infinite space (literal outer space).
Yes, or more precisely, the fifth stage of samma-samadhi is the OOBE, and the first stage of the OOBE is really experienced being Out-of-Body on the material plane, but can include traveling anywhere in space to other planets, etc, so, I am OK with 'infinite space' as a translation of the 5th stage of samma-samadhi.
I revisited the GWV's writeup on samadhi stages and it says the 6th jhana is infinite time - which is not correct, as the 6th Buddhist jhana is infinite consciousness. I was wondering what the experience of infinite consciousness is like?
The problem with translation is most translators don't even meditate, and most of them were just scholars, and of those who are monks, they generally put the robes on and pretend to be holy, so none of them have any experience at all with the 8 stages of samadhi. Whereas, I have a degree in linguistic anthropology, and I have been a rigorous contemplative for 50 years, and I have had consistent depth in meditation for over 50 years, which has included daily Out-of-Body experiences. So, I try to map my experiences in samma-samadhi.
So, back to infinite consciousness as a definition of the 6th stage of samma-samadhi. I'm OK with infinite consciousness as a definition, but what does that mean? In my experience of being Out-of-Body in space and looking out at the vastness of space, which is full of stars, but I felt each point of light was a being which emitted immense love. So, infinite consciousness and love is OK with me.
Also, what is no-thingness and no perception nor non-perception?
This is a good question. I find these definitions are confusing because they don't map onto my experience. The definitions suggest unconsciousness; however, that has not been my experience. Instead my experience was becoming one with all of that infinite field of light and love so that I was all of that. This definition fits the larger description of experience of mystics.
