This form of yoga, like every other, has a set number of poses that follow a process. Each pose needs to be held for a particular time. In yin yoga, beginners are required to hold each pose for anything between 45 seconds to about 2 minutes. Those who have been practicing this for a while, sometimes go up to even 5 minutes. In comparison, this form of yoga is far slower as compared to the original one. When coming out of a pose there will be a natural sense of fragility - we have been deliberately pulling the body apart and holding it apart. The sense of relief is to be expected, and even enjoyed. Yes, despite some myths to the contrary, you are allowed to enjoy your practice! Smile when you come out of the pose! Laugh - cry even. Thank the Buddha, Jesus, Allah, "Om Namah Shivaya!" Enjoy this moment.
