Joshi's initial learning was from his uncle Maheshwar Shastri Joshi in Pune. He mastered Sanskrit grammar before the age of twenty, passing various examinations from Bengal, Baroda and Pune. He began teaching at the Poona Sanskrit College and served as its principal from 1947 to 1955.
Joshi was the teacher to Daniel Ingalls in 1950s. Ingalls was very impressed with Joshi and persuaded him to come to Harvard University.
