Flipping through the pages of the internet, I just came across a great article on Kirtan in Psychology Tomorrow magazine - At the intersection of art and psychology, by The Rev. James Reho Ph.D..
http://www.psychologytomorrowmagazine.com/kirtan-chanting/
The article talks about the meaning of Kirtan, it’s timeline in history, the science behind the sounds and instruments, and a unique look at the comparisons between other meditative dialogues.
As Kirtan mainstreams, there will be more and more opportunities to participate and practice in the meditative state that the call and response form of yoga invokes. I can’t help but smile and rejoice “Halleluiah”, or should I say, “Hari bol” to that!
