Becoming fascinated with them will just be a distraction . In a way they are a good thing and a sign of progress up to a point , but also in a way they are unimportant and very normal . I ' ve also experienced the same sensations occurring outside of meditation while reading , or experienced them building up within the first few breaths of sitting down to meditate . It ' s just something you have to live with for a while and eventually , at a certain point , it passes . Meditation sessions become less energetic , sleep becomes normal again , etc . During these times if you ' ve built an attachment to the sensations as a marker , you may form the belief that your meditation isn ' t going as well as it used to . As far as the experiences being related to purification , I ' m not really convinced that there is much evidence to support that they are related . It ' s just one of the many things that can happen . There is certainly a reason that it happens , but knowing and understanding the reason is unnecessary and may just end up being a distraction . In my experience , the increased energy is associated with specific parts of the path and it ' s stronger at certain times than others , so you ' ll probably notice at a certain point that you ' re not as sensitive to it . It ' s something that tends to come and go and only one of the many , many strange things that can happen during meditation . On a side note , I also get regular acupuncture treatment and yes the sensations of energy are very similar , and I think related . Acupuncture during AP I found was even more fascinating because of the increased awareness of subtle energy . The same sensations that would occur during meditation would be rerouted manipulated by the needles .
