Sridhara or Sridharacharya was the son of Baladeva and Achoka, residents of Bhuri Srishti (Bengal). He wrote Nyaya Kandali, the commentary on Prasasti Pada Bhashya of Vaisheshika Sutra.
Sridhara has refuted the Buddhist criticism of the Vaisheshika system. He was also an authority on Vedanta, Vyakarana, and the Nyaya Mimamsa. His other works include Advaya Siddhi, Tattva Prabodha, Tattva Samvadini and Sangraha Tika, which have been referred to in his Nyaya Kandali. Nyaya Kandali has been criticized by some other writers such as Rajashekhara.
Another Sridhara (14th Century AD) was known as Sridhara Swami, who wrote commentaries on Bhagavata Purana, Vishnu Purana (titled Atma Prakasha) and the Gita (Subodhini). He was a disciple of Paramananda.
