A week of practicing Kriya Yoga

[TheSelf]

Hey guys, my first post here in this awesome forum,

Mystory is that for a long time i could feel some tingling sensations on my forehead, like whenever i focus on it, immediately the feeling would start, but i didn't know what's that until i researched about it and figured out that its about pineal gland and third eye, so i researched more and also saw Leo's vid about Kriya Yoga, and really really interested getting into sprituality after reading alot about all these, and started practicing the techniques (pranayama, maha mudra talabiya mudra), on  my third session of practising pranayama (moving prana up down version) i started feeling intense vibrations in my head and also my chest and prana first on my spine ( tingling or like worms moving underneath your skin kinda feeling) then in the next day i could feel these in my neck, hands, feets, face even on my eye lids,whenever i focus and imagine the prana moving up down( can get intense depends on how long i do it), if i focus on my forehead in just a few minutes the feeling can get very intense i also experienced some intense headaches for like 2 days but it went away, and also i feel a lot of vibrations mostly in my head after  practicing pranayama almost in whole body, so i wondering if is all these normal for this very short time (almost a month of breath focusing and a week of Kriya Yoga plus a few days of self inquiry) and am i on the right path??   Btw i have almost a calm monkey mind( even it did get much more calmer after started getting into these stuff,btw I'm an artist and practicing art for years and living alone with very little social interactions with others maybe hanging out with friends once every two three weeks, maybe my life style is kinda releated that Kriya Yoga seems working really good so far?! So any opennions and advices are much welcome.
