O'Dog, Thanks. I just googled metta as I had not heard of it before, Seems powerful and done in a healthy progression.
I'm sure you've heard of Brain Waves,Electrical vibrating cycles per session (Hz): Beta, alpha, theta, delta,
A few years ago (#?) another was discovered: Gamma (40Hz) and was later confirmed in a University of Wisconsin, Madison study authorized by the Dali Lama, measuring hundreds of Tibetan Monks in deep meditation on "Loving compassion." Sure enough: a new level -Gamma, which resulted in what was labeled Binding. Through binding the brain gathers and integrates iinfo from all our senses and binds them into a cohesive whole.
Going on and on again...
Google Dr. Jeffrey Thompson. I use his cds twice daily. As an aid. All proven, all very scientific and they have helped me greatly. fwiw
