Vajramuni was a college dropout and held a degree in cinematography. A product of the Kannada amateur theatre, he performed regularly in the mid-1960s for
Gubbi Veeranna's theatre company among others. He impressed
Puttanna Kanagal with his performance as
Ravana in Kanagal Prabhakar Shastri's play
Prachanda Ravana who offered Vajramuni a role in the film
Saavira Mettilu. The film however got shelved, but was completed by
K. S. L. Swamy and released in 2006. Kanagal eventually cast him in
Mallammana Pavada (1969), which would become Vajramuni's first release. Producers insisted that
Udaykumar would be a better choice to match to
Shivaji Ganeshan who played the role in the Tamil version, but Puttanna insisted that it had to be Vajramuni. He went on to cast Vajramuni again in
Gejje Pooje (1969). Impressed by his performances in these two films, director
S. Siddalingaiah cast him in his 1971 film,
Thayi Devaru. Vajramuni acted in a number of films such as
Mayura,
Sampathige Saval,
Daari Tappida Maga,
Premada Kanike,
Giri Kanye,
Shankar Guru and
Aakasmika with
Rajkumar. == Personal life ==
