I just want to ask that is there any university in India or outside India which is able to award Ph.D. in Hinduism. As whatever I searched on Google, there is no university in the India. Please suggest if there is any.
Yes, Hindu University of America offers a Doctoral Degree in Hinduism: http://www.hua.edu/doctorate_programs.php
the topic of religion comes under term "Philosophy" and there are many Indian universities offering doctoral studies on any subject including Hinduism. You need google using the key word "Phd + Philosophy". alternatively you can also search using term "Indologist'
You can browse the weblink apaonline.org/?page=gradguide which has data on philosophy education programs primarily in USA and other locations.
