Vachaspati Mishra (1425-1480) Smrti scholar and logician of Mithila, was born in the Samouli branch of the Palibar family. He wrote a total of ten books on logic and thirty-one books on religion. A fresh compilation of texts of Aksapadasutra titled Nyayasutroddhara and explanatory notes on the same title Nyayatattvaloka are two of his erudite works. At the behest of Padmavati, wife of King Prataprudra of Panchaleshwar, he wrote Prakash, a book of commentary on Nyayaratna by Manikanthamishra. His other books on logic are Pratyaksanirnaya, Anumananirnaya, Shabdanirnaya, Khandanoddhara (a reply to Khandanakhandakhadya by Shriharsa), Chintamaniprakasha etc.

The most famous of the works of Vachaspati Mishra are his books on the Smrti which earned him the title of Smarta Vachaspati in the learned society. Among his books on the smriti the ones that deserve special mention are: Acharachintamani, Dananirnaya, Dvaitanirnaya, Bibadachintamani, Shuddhichintamani, Byabaharachintamani etc. Bangla treatises on the Smrti are found to have been influenced by these books. Apart from logic and smrti, Vachaspati wrote books on other subjects as well. Among them the most notable ones are Sahasradhikarana written on the philosophical treatise called Mimangsa and a book of poems titled Pitrbhaktitarangini. [Satyanarayan Chakraborty]
