This paper examined the relationship between the word aśeṣajñāna in the final chapter of the Tattvasaṃgrahapañjikā (TSP) and omniscience based on passages in related literature. The following became clear. (1) TSP uses the śeṣa / aśeṣa understanding seen in the Pramāṇavārttikapañjikā (PVP) and the Pramāṇasamuccayaṭīkā (PSṬ). (2) TSP is slightly different from PVP and PSṬ with regard to the words used when discussing śeṣa. (3) TSP thinks that śeṣa is jñeyāvaraṇa, and that one cannot become omniscient without eliminating it. (4) PVP, PSṬ and TSP say that one whose knowledge is aśeṣa can expound the four truths through various means. (5) These texts present aśeṣajñāna as a determinant of whether one can skillfully preach and of the difference between the Bhagavat and śrāvakas / pratyekabuddhas. (6) These texts do not think that the Buddha is merely a knower and an expounder of the four truths. (7) When considering post-Dharmakīrti views of the omniscient Buddha, understandings of aśeṣajñāna should not be ignored.
