Puranapanda Srinivas has penned a spiritual treatise on Lord Hanuman. Titled 'Nenunnanau', it comes from the writer of the outstanding 'Mahamantrasya'.

Srinivas is a revered and learned man who has brought out acclaimed spiritual works over the years. 'Nenunnanu' is one of his best-known works on how to worship Anjaneya Swamy. The 'maha grantham' has come in for praise various quarters and Vaarahi Chalana Chitram's Sai Korrapati garu and Rajani Korrapati's support for this spiritual endeavour is worthy of mention.

SS Rajamouli, Young Tiger NTR and Nandamuri Balakrishna, too, have endorsed the awesome work.

The spiritual treatise has been in much demand not only in the Telugu States but from devotees of Lord Hanuman from other parts of India as well.
