76 BRAHMASPHUṬA SIDDHĀNTA & KHAṆḌAKHĀDYAKA bījam 51—59 Bhāvita-bījam 60—63 Varga-prakṛtiḥ 64—74 Udāharaṇāni 75—102 XIX Śaṅkucchāyādijñanādhyāyaḥ 20 20 XX Chandaścityuttarādhyāyaḥ 20 19 XXI Golādhyāyaḥ 70 70 Sāmānya-golaprakara- ṇam 1—16 Jyā-prakaraṇam 17—23 Sphuṭagati-vāsanā 24—30 Bimba-sādhanam 31—35 Grahaṇa-vāsanā 36—48 Golabandhādhikā- raḥ 49—70 XXII Yantrādhyāyaḥ 53 57 XXIII Mānādhyāyaḥ 12 12 XXIV Sañjñādhyāyaḥ 13 13 Total 1016 1022 In one of the verses, Brahmagupta states that he has composed the treatise containing 1008 verses. Sudhākara Dvivedī has given the total as 1021, whereas he says, this number according to Brahmagupta's own statement should be 1020. If one de- ducts the concluding 12 verses of the Sañjñānadhyāya, the num- ber should be 1008. Sudhākara Dvivedī, in his addition of the Brahma-sphuṭa- siddhānta (published in the Paṇḍita, 1901 and 1902) gives as a supplement a small treatise of Brahmagupta known as Dhyāna- grahaṇopadeśādhyāya or Dhyānagrahaṇādhikāraḥ which has 72 verses. It would be worthwhile to give here the details of the Khaṇḍakhādyaka also, a book of Brahmagupta about which we have spoken so much. The titles to the chapters have not been indicated in the Text ; most likely they have been assigned by the commentator, Pṛthūdaka Svāmī known as the Khaṇḍakhā- dyaka-vivaraṇam.
