If you are taking admission in private Ayurvedic colleges, then there are no bonds as such. But for the state government or central funded college, you may have to sign a bond. So if you leave the sit after admission, then you have to pay the bond money in order to leave the course.

I would recommend you to contact the college you are getting and get the rules from them. They can provide you more informations.
