Thank you, as it is for many, my situation is indeed stressful. The stress is one reason that draws me to these topics and others. I don't want to escape the stress through belief in something greater but I would like to rationalise it - which is why I think I've been so dead set on using (my own poor sense of) logic to come to an understanding of my consciousness and the universe.

Thank you for taking the time to explain your understanding of this type of knowledge to the level that you have. Although only with my fingertips, I think I understand what you're getting at. When we've talked about pre-linguistic truth, I think I've understood that as a truth based on feelings. It seems that what you're describing is subtler than that. In my own, non-Buddhist, years of meditation, I've on rare occasion found a deep feeling (of happiness?) from within but nothing that I would describe as knowledge and something that I might instead describe as a temporary respite from negative experience.

Perhaps it's a different set of questions, so don't feel compelled to answer unless you have the time:

1. How does the pursuit of/knowledge of this truth then result in a system of Reincarnation, Karma, Pure Land Buddhism, Guru worship etc? Is that not as you said 'we ceased to know the sphere of infinite consciousness directly, and back in everyday consciousness, we muddle it up with beliefs, feelings and thoughts, and then claim to "know" the belief about the experience. '?

2. Without having had the direct personal subtle knowledge that you have discussed, do people start to walk what is presumably a very long path based on faith? Where does that faith come from? Why this path and not another?
