Yoga place in east India

Hello.

I’m in Kolkata now. I am looking to do some sort of Yoga “retreat” or something of the type in an Ashram.

I am not looking for a “vacation”, but a serious place to practice Yoga, meditation and spirituality. I am well aware that some places have a rigid routine and I am willing to follow.

The problem is that I didn’t plan ahead and I really don’t know where to start. Any suggestions?

Even if I can’t find anything here, I can go to other cities in India if necessary.

Thanks a lot!
