"Meditation is calming the reptilian brain. We have all got three brains in us: One is a reptilian brain, which is about 420 million years old, our mammal brain is half that old, and our most recent one is the intellectual creative brain. The reptilian brain is very prominent; it runs our respiratory and sexual systems; it is action and reaction. We have to calm this reptilian brain so that the mammal brain, which is the brain of compassion and is here to bring kindness and kinship and bonding, can function. I mean, reptiles do not make good lovers; that is not their thing. Meditation allows us to treat the reptilian brain well: 'Nice crocodile, nice crocodile.' When we calm the crocodile, then the mammal brain can assert itself. Meditation is not just for professional monks; it is a survival mechanism for us all, especially in this time of crowdedness and rubbing shoulders with people of different faiths and traditions. We all have to learn to calm our reptilian brain."
