wow that's weird looking at the shape of your eye sockets like that, i feel like an owl or something.

pretty cool effects, you just gotta try to be aware of everything in your vision. my vision kept kinda "twitching" every so often, so maybe there was too much tension in my eyebrows (being raised) or my eyes (trying to look to high up). i'm not sure if i understand this part:

"When you breath in, close the airway to your throat with the back of your tongue" -- how do you do that? I mean I can breathe in with just my nose, but the tongue thing is weird.

Anyway I wasn't sure if it had worked at first when I stopped after a minute or so... until my dad entered the room and started talking to me and all of a sudden I realized I was feeling really high

All in all though, I think I prefer regular meditation. This technique was interesting and I'll try it again, but I feel like there was too much muscular tension in my face from trying to do it right; in my jaw and eyes and forehead, like I was trying to stretch my face too long.
