Having a great memory, Giridhar learnt all 700 verses of Bhagavad Gita at in 15 days when he was 5 years old. His neighbour, Pandit Murlidhar Mishra, helped him. On the Janmashtami day in 1955, he read out the whole Bhagavad Gita. By accident, 52 years after the day he learnt the Gita, he released the first ever Braille form of Gita at New Delhi on November 30, 2007, with the real Sanskrit text and a Hindi series of comments. When Giridhara was seven years old, he learned the whole Ramcharitmanas of Tulsidas (close to 10,900 verses) in 60 days. His grandfather helped him. On Ram Navmi day of 1957, he spoke the whole book while not eating food because of religious reasons. After that, Giridhara went on to learn the Vedas, Upanishads, books on Sanskrit grammar, the Bhagavata Puran, all books of Tulasidas and many other books.
