4.320.000 a Maháyuga.
[paragraph continues] So that these periods resolve themselves into very simple elements: the notion of four ages in a deteriorating series expressed by descending arithmetical progression, as 4, 3, 2, 5; the conversion of units into thousands; and the mythological fiction, that these were divine years, each composed of 360 years of men. It does not seem necessary to refer the invention to any astronomical computations, or to any attempt to represent actual chronology.
24:5 The details of these, as occurring in each Manwantara, are given in the third book, c. 1 and 2.
24:6 'One and seventy enumerations of the four ages, with a surplus.' A similar reading occurs in several other Puráńas, but none of them state of what the surplus or addition consists; but it is, in fact, the number of years required to reconcile two computations of the Kalpa. The most simple, and probably the original calculation of a Kalpa, is its being 1000 great ages, or ages of the gods: ### Bhavishya P. Then 4.320.000 years, or a divine age, x 1000 = 4320.000.000 years, or a day or night of Brahmá,. But a day of Brahmá is also seventy-one times a great age multiplied by fourteen: 4.320.000 x 71 x 14= 4.294.080.000, or less than the preceding by 25.920.000; and it is to make up for this deficiency that a certain number of years must be added to the computation by Manwantaras. According to the Súrya Siddhánta, as cited by Mr. Davis (A. R. 2. 231), this addition consists of a Sandhi to each Manwantara, equal to the Satya age, or 5.728.000 years; and one similar Sandhi at the commencement of the Kalpa: thus p. 25 4.320.000 x 71 = 306.720.000 + 1.728.000 = 308.448.000 x 14 = 4318.272.000 + 1.728.000 = 4320.000.000. The Pauranics, however, omit the Sandhi of the Kalpa, and add the whole compensation to the Manwantaras. The amount of this in whole numbers is 1.851.428 in each Manwantara, or 4.320.000 x 71= 306.720.000 + 1.851.428 = 308.571.428 x 14 = 4319.999.992; leaving a very small inferiority to the result of the calculation of a Kalpa by a thousand great ages. To provide for this deficiency, indeed, very minute subdivisions are admitted into the calculation; and the commentator on our text says, that the additional years, if of gods, are 5142 years, 10 months, 8 days, 4 watches, 2 Muhúrttas, 8 Kalás, 17 Kásht́hás, 2 Nimeshas, and 1/7th; if of mortals, 1.851.428 years, 6 months, 24 days, 12 Náris, 12 Kalás, 25 Kásht́has, and 10 Nimeshas. It will be observed, that in the Kalpa we have the regular descending series 4, 3, 2, with cyphers multiplied ad libitum.
25:7 The Brahma Vaivartta says 108 years, but this is unusual. Brahmá's life is but a Nimesha of Krishńa, according to that work; a Nimesha of Śiva, according to the Saiva Puráńa.
