This set is my favourite of Maya's dvds, so far. You have to try them to know. They open up the 4th and 5th chakras and engender a wonderful sense of 'coming home', rekindling distant memories of the true peace that existed before thought began. Not very physically demanding though, at least not once you've mastered the 'breath of fire'. I don't feel really stretched, but I love them. During the day, I think about doing these when I get home at night. I try to alternate with the other chakra series though, for balance. Guess that's right.
