13. DEMONSTRATION OF THE CONSTANT
OF PRECESSION
The caturyuga of 4320000 years is the unit of reference for determining
the constant of precession used in the construction of Hindu cosmological
time cycles.
The constant of precession is
This is equivalent to one degree of precession in50".4 = 0°.014 = 7/500 degrees of precession per sidereal year.
The relevant infrastructure of the kalpa period (see Table III) is71 3/7 = 71.42857... sidereal years.
In the interval of 1/14 kalpa there are1 manu = 71.4 caturyugas 1/14 of introductory dawn = 0.02857... caturyugas --------------------------------------- 1/14 kalpa = 71.42857... caturyugas.
Other relations of interest are(71 3/7)(4320000)(0°.014) = 4320000 degrees of precession = 12000 precessional years.
1 precessional year = 25714 2/7 sidereal years 7 precessional years = 180000 sidereal years = 1 week of precessional years = 126 = 7×18 cycles of the 3rd mean motion of the Sun 16.8 precessional years = 1 kaliyuga 7×24=168 precessional years = 1 caturyuga 168000 precessional years = 1 kalpa.
