Yoga Bliss

I'm sure the name "Yoga Bliss" has been used before. But it was mentioned or referred today in our yoga teacher training. We were discussing the Kripalu style of yoga where you "ride the wave of sensation". Briefly explained, it means that you do some repetitive motion into the posture, then hold the posture for as long as you can. When you feel like you can't hold the posture any longer, hold for another breath. If you continue to hold after a breath, you start to feel bliss. I think there is some psychology in there. Some people feel a sense of accomplishment, pride, etc. afterwards because they went a little further, held it a little longer than before.
