The other day I watched this kundalini with mantra initiation video by this guru and I felt something happen in my body. First my vision went a little blurry and then all of the sudden I felt a lot of joy out of nowhere. Very interesting experience. I have had some sensations like that during meditation, but this came right after watching those videos. I have been practicing yantra yoga for a few years now and maybe this is why i got this effect very quickly. It was a very interesting experience to say the least. I did not really think anything would happen as the whole thing sound a little weird to me to give kundalini initiation via youtube, but I did feel something. I did a little research and apparently this guru gives out all his teaching for free, which i find really interesting. Anyways, here are the vids:
