The bliss seemed like a side-effect; it was nice but I wasn't trying to elicit it as much as it was generated by the calm.

Yeah, the forehead-flame was/is really bizarre. I did some Google searches for it and didn't find much of anything that didn't seem like pseudo-science (look up "Ajna chakra" and you'll see what I mean...)

It's always hard to convey to people that it was very different from a mental image / thought / feeling in that it actually feels tactile, in the same way that if you had a rock in your shoe, you wouldn't confuse it for anything else--I just don't know what this "rock" is made of; it could certainly be a creation of my mind, but it doesn't present itself that way. It's easy to ignore, so I ignore it.
