In the Udayendiram copper plates of Nandivarman II, Simhavishnu was a devotee of Vishnu. This is a noteworthy point as his son Mahendravarman I was a Jaina who opposed all the Saivaite practices before being converted to Saivism. Simhavishnu's portrait can be seen in the stone engraving at the Adivaraha Mandap, an elegant shrine at Mahabalipuram. The monuments and temples in Mahabalipuram are achievements of the Pallava dynasty, and they still exist in Tamil Nadu. Simhavishnu was succeeded by his son Mahendravarman I.
