Tattvabindu ( Devanagari: तत्त्वबिंदु ) is an independent treatise of the Indian philosopher Vachaspati Mishra on Sanskrit grammar, which focuses on Mīmāṃsā theories of sentence meaning.
[1] In Tattvabindu Vachaspati Mishra developed the principles of hermeneutics, and discusses the "theory of meaning" for the Mimamsa school of Indian Philosophy.
Vachaspati Mishra wrote his Tattvabindu with the aim of clarifying Abhihitanvayavada, after facing challenges against it from the perspective of other theories such as Sphota and especially Prabhakara's Anvitabhidhanavada.
Thus, Vachaspati Mishra properly explains the effective cause of word perception and establishes Abhihitanvayavada.
Vachaspati Mishra in his work Tattvabindu examines five competing theories of linguistic meaning.
