Why does my body vibrate 2 hours after chakra meditation/Kundalini?
Intensive meditation does have effects, otherwise nobody would practice it… There are many different types of meditation, and although chakra meditations and kundalini practices are done quite a lot these days in the west, their origin lies in very advanced practices. Best is if you learned this from a qualified teacher, to check with that teacher. If you taught this yourself, I would advise to start looking for a qualified teacher (not someone who picked it up during a holiday in India or so). I suspect that you may actually be raising a bit of kundalini or other energy, but you need to be aware that this can be dangerous without proper guidance. So until you find a good teacher, better to stop this technique. For the time being, if you want to stop it, it may help to focus the energy towards a spot slightly under your belly-button, where it can usually be stored with little harm.
