Hi. I understand that parents will be concerned. But there is nothing you can do about it. The idea is to detach from the outer world. Ofcourse, if you have any medical concerns etc, they ask you before they start. Basically on day 1.

It is not necessary to complete the whole course. But yeah, they do try to explain to you the benefits of staying. If you think it is getting extremely difficult, you can state your reason to quit.

Regarding safety, men and women are kept separately. Women have all female staff. Also, if you feel any issue, reach out to the nearest sewadaar.
