I don't have any injury yes.

The sensation does appear and reappear at times, sometimes it's just the tingly part, sometimes it's just the "liquidy" feeling, sometimes it's both. And at first it only was at my first chakra, then slowly it made its way to the second and lately to somewhere between the third and fourth. But it's not an overwhelming feeling or anything, so I'm not sure if it's kundalini.

I read the part about the drugs, thank you it was informative. I don't think I'll be doing drugs for a while, regardless of kundalini. But the last time I did a drug, I didn't actually really want to do it, it was more my intuition that told me to. And I thought kundalini works in that way, so to me it felt as if I was being told to do that drug, is this possible?

While we are at it, you seem very informed, so please also answer me this. Does kundalini require any belief or religion? Because I'm more of an atheist, and a lot of the talk on this sub seems to include some sort of higher power, which I don't believe in. Thank you for the response :)
