Rajdhar proved himself to be a ruler of spiritual leanings. Avoiding the battlefield and having little interest in the administration of his kingdom, he instead devoted himself to religious pursuits. A patron of Vaishnavism, under his rule the influence of the sect spread significantly throughout Tripura. A temple to Vishnu was constructed in Udaipur and eight Brahmins were employed to perform devotional songs before the idol perpetually. Its gardens were adorned with fruit and flowering plants and the Maharaja visited it daily. Rajdhar was also considered notable for his great respect for Brahmins, participating in religious discussions with the 200 in his court and distributing significant amounts of land to them, in spite of opposition from his nobles.
