I'm sure many of you heard of this form of meditation that is practiced by some Tibetan Buddhists from the same way I just head of it, through an article about neuroplasticity that said that monks who have practiced this have created a permanent increase in their amount of gamma brain waves. In the article I read they said it was focusing unlimited compassion and love on all living beings. I'm interested in why this is, so I tried to google non-referential compassion for some details but I don't get anything, just links to similar neuroplasticity articles. I'm hoping someone here might now and provide some more information. Anyone?
I would recommend The Mind and the Brain. It might not directly alleviate your itch, but it will surely provide more insight as well as a thought-provoking read. http://www.amazon.com/Mind-Brain-Neuroplasticity-Power-Mental/dp/0060393556
