   • The Nature of Pakṣābhāsa (Fallacies of the Subject): Discussing various ways in which the subject of an argument can be flawed (e.g., contradiction with direct perception, inference, scripture, common usage, self-contradiction, unknown qualifiers).
   • The Nature of Hetvābhāsa (Fallacies of Reason): Categorizing and explaining various logical fallacies in the middle term of a syllogism (e.g., impossibility, undividedness, irregular pervasiveness).
   • The Nature of Dṛṣṭāntābhāsa (Fallacies of the Example): Detailing flaws in the illustrative examples used in arguments.
   • Proof (Pramāṇa): Primarily focusing on perception (pratyakṣa) and inference (anumāna) as the two valid means of knowledge.
