56 PERSONAL REFERENCES OF BRAHMAGUPTA
anti-authoritative versions of astronomical systems :
Evam Varāhamihira-Śrīṣeṇācāryabhaṭa-Viṣṇucandrādyaiḥ
Lokaviruddhamabhihitam Veda-smṛtisaṃhitābāhyam.
At one place, he mentions the difference between the calculations
based on the system of Āryabhaṭa and the Pañca-siddhāntas
(Five systems) : Pauliśa, Romaka, Vasiṣṭha, Saura, and Paitāmaha.
(BrSpSi. XIV.46).
Brahmagupta was also familiar with the Jaina systems of
astronomy; for example, at one place he uses the term "Jinoktam"
(i.e., one propounded by the Jainas) : He repudiates the concept
of two Suns and two Moons "Dvāvarkaindavau" (do canda do sujja)
(BrSpSi. XI.3) as enunciated by the Jainas.
At several places we find a reference to the Vasiṣṭha-sid-
dhānta (BrSpSi. XI.49, 50; XXIV.3)
Wherever, Brahmagupta has to press for his views in pre-
ference to the views of others, he uses the words Brāhma or
Brahmokta : BrSpSi.
Brāhma : I.32; X.62; XI, 61; XVI.37
Brahmokta : II.31, 33; X.63, 69; XV.59; XVI.33
