 ``` CHAPTER XLII. 375 It is possible that Paulisa simply mentions this method as one among others, and that it is not that one in par¬ ticular which he himself adopted. A translation of his whole work into Arabic has not hitherto yet been under¬ taken, because in his mathematical problems there is an evident religious and theological tendency, Pulisa deviates from the rule which he himself gives PuUsa cai- , , 1 f 1 dilates how when he wants to compute how many ot our years have much of the elapsed of the life of Brahman before the present kalpa. man has Up to the time of his writing, eight years five months forethepre- and four days of a new kalpa had elapsed. He counts ^'^^ ^'^"' 6068 kalpas. As, according to him, a kalpa has 1008 caturyugas, he multiplies this number by 1008 and gets 6,116,544 caturyugas. These he changes into yugas by multiplying them by 4, and he gets 24,466,176 yugas. As a yuga, according to him, has 1,080,000 years, he multiplies the number of yugas by 1,080,000, and gets Page 189. as the product 26,423,470,080,000, i.e. the number of years which have elapsed of the life of Brahman before the present kalpa. Perhaps it will seem strange to the followers of Criticisms " on this cal- Brahmagupta that he (Pulisa) has not changed the ouiation. caturyugcts into exact yugas, but simply changed them into fourth parts (by dividing them by 4), and mul¬ tiplied these fourth parts by the number of years of a single fourth part. Now, we do not ask him what is the use of repre¬ senting the caturyugas as fourth parts, inasmuch as they have no fraction which, in this manner, must be reduced to wholes. The multiplication of the whole caturyugas by the years of one complete caturyuga, i.e. 4,320,000, would have been sufficiently lengthy. We, however, say that he would be correct in doing so if he had not been influenced by the wish of bringing the elapsed years of the present kaljxt into relation with the last-mentioned number, and multiplied the complete elapsed manvantaras by 72 in agreement with his ```
