No. additive months and
that of subtractive days.
38. (In a great yuga) there are 1,593,336 additive months and 25,082,252 subtractive days.

No. of Solar months in a
yuga and the way to know
the No. of terrestrial days.
39. There are 51,840,000 Solar months in a great yuga, and the terrestrial days are the sidereal days diminished by the Sun's revolutions.

40. The revolutions of the planets, the additive months, the subtractive days, the sidereal days, the lunar days and the terrestrial days (mentioned above) separately multiplied by 1000 make the revolutions, the additive months &c., in a Kalpa, (because a Kalpa consists of 1000 great yugas.)

41 & 42. In a Kalpa, there are 387 revolutions of the Sun's Apogee (about the Earth), 204 of Mars' apogee, 368 of Mercury's apogee, 900 of Jupiter's apogee, 635 of Venus' apogee and 39 of Saturn's apogee.

Now we proceed to mention the retrograde revolutions of the Nodes (of the planets Mars, &c.)

43 & 44. There are 214, 488, 174, 903, 662 revolutions of the Nodes of the planets Mars, Mercury, Jupiter, Yenus and Saturn respectively. We have already mentioned the revolutions of the apogee and node of the Moon.

The number of the solar
years elapsed from the time
when the planetary motions
commenced, to the end of
the last Krita yuga.
45, 46 & 47. Collect together the years of the six Manus, with their six Sandhis, and the Sandhi which lies in the beginning of the Kalpa, those of twenty-seven great yugas of the present Manu named Vaivaswạta and those of the Krita yuga; and subtract from the sum, the said number of years of the Gods, reduced to solar years, required (by the God Brahmá) in the creation of the universe, (before the commencement of the planetary montions,) and the remainder 1,953,720,000 is the number of solar years before the end of the Krita yuga.
