12. DEMONSTRATION OF THE
3RD MEAN MOTION AND SIDEREAL YEAR
The kaliyuga of 432000 years is the unit of reference for determining
the length of the sidereal year in Hindu cosmological time cycles.
There are seven rotations of the 3rd mean solar motion, counted separately through the sidereal year, in 10000 sidereal years. For a single year the count is 0.2563795... diurnal revolutions of the Earth. For two years it is 2(0.2563795...). For a complete rotation there are
The integral part of this interval, 1428 years, summed 432000(7) times is equal to 14 manus (see Table III). Thus366.2563795... 10000 -------------- = ----- = 1428 4/7 sidereal years.2 0.2563795... 7
The fractional part of this interval, 4/7 years, summed 432000(7) times is equal to the introductory dawn (see Table III). Thus,432000(7)(1428) years = 4318272000 years.
Thus, 1428 4/7 weeks of kaliyugas = 1 kalpa.432000(7)(4/7) years = 1728000 years.
