Can anyone tell me that is Banasthali University only for girls?

Let me google that for you.

Yes Banasthali Vidyapith is only for girls, their education program is based on the concept of "Panchmukhi Shiksha" for girls. This Panchmukhi Shikhsha contains 1) Physical
2) Practical
3) Aesthetic
4) Moral
5) Intellectual

Why did you ask the question and then sign on under a 2nd user name and answer your own question.

That really gives a bad impression.
