ब्राह्मस्फुटसिद्धान्त (ब्रह्मगुप्त - शून्य, कुट्टक, बीजगणित एवं सम्पूर्ण २१ अध्याय सान्वय सटीक)

94 BRĀHMASPHUṬASIDDHĀNTA & KHAṆḌAKHĀDYAKA (e) Two quotations from the Uttara Khaṇḍakhādyaka rel- ating to the celestial co-ordinates of Canopus and Sirius (Sachau's Alberuni, Vol. II, p. 91). Present manus- cripts do not show these stanzas, which are probably the same as stanzas 35-36 and 40 of Chapter X of the Brāhmasphuṭasiddhānta. (f) Two quotations from the Khaṇḍakhādyaka proper as alleged by Alberuni (Sachau's Alberuni, Vol.II, p. 116). According to Āmarāja, the first is a couple of stanzas of which the author is Bhaṭṭotpala and not Brahmagupa. The second quotation cannot be traced. These relate to finding the possibility of an eclipse whether of the Sun or of the Moon. (g) Two quotations from the Khaṇḍakhādyaka proper as asserted by Alberuni (Sachau's Alberuni, Vol. II. p. 119). These relate to finding the Lords of the year and of the month. According to Āmarāja the rules in question were given by Bhaṭṭotpala and not by Brah- magupta. Pṛthūdaka in his commentary on the first chapter at its concluding portion says ; “In this work the Khaṇḍakhādyaka, the teacher (Brahmagupta) has not given the rules for finding the Lords of the year and the month¹.”
