Naran S Balakumar
Chin Mudra activates the Apana, meaning it facilitates downward movement of our prana.
In the morning, if you have a constipation or difficulty in passing motion or going for bowels, be in this Mudra, and chant "MOVE ON".
At that time of motion, chant “GENTIAN, MOVE ON” so that you will be satisfied with your bowels. Gentian is a Bach Flower Remedy.
You can also chant “JO” – a Chinese mantra.
Chin Mudra can be done after hernia operation. This cannot heal hernia by itself. First you need to do the operation. Those who are having hernia should not exert themselves while passing the motion.
