I'm a rationalist or skeptic, but I believe in meditative states and kundalini syndrome, because I have had both happen to me. I can't offer any objective proof, and would rather that people left my brain alone if I was to die or something. I've been in countless meditative states or samadhis. I also lean towards the idea that enlightenment is real, and exists as a rare medical condition and perpetual blissful near death experience. I have ticks that come and go after accidentally bringing kundalini syndrome on myself in 2011. I mostly don't meditate, or mess around with some of the techniques that I used to, there are aspects of meditation that scare me. I think if enlightenment is real, realizing it would probably involve moments of absolute fear, since that I think that the type of meditation necessary to realize it is related to near death experience.
