Intro
Prior to the construction of Complete Relativity (CR) I did not know anything about the Vedic
culture. It was only later brought to my attention.
What was a striking revelation is not only that the philosophy of Bhagavad Gita agrees almost completely with
mine, but there are agreements in numbers too.
Except for reading Bhagavad Gita, I haven't thoroughly explored this literature, but here are some values I've found to be in agreement with my theories.
Numbers
Period of existence
I have originally assumed that the 3rd order period of existence pulses of the Solar System is 1.51±0.06 million years, equal to what I believe is the
average half-life of ^{10}Be (beryllium isotope) over evolution of the local universe.
This turned out to also be the average of Satya and Treta *yuga*:
$\displaystyle {{(Satya\, yuga) + (Treta\, yuga)} \over 2} = {{1728000 + 1296000} \over 2} = 1.512 * 10^6\, years$
I've known that period of existence is an average value and in reality it should oscillate. After inspecting Vedic literature, I find it likely that this one oscillates between Satya and Treta.
The age of Earth and periodicity of extinctions
After I have accounted for pulses of strong evolution which temporarily affect decay rates of elements, I have calculated the real age of Earth to be 4.29409±0.05 * 10^{9} years.
This is also equal to hypothesized 1st order period of existence, and it agrees well with 1 aeon (*kalpa*) = 4.32 * 10^{9} years.
Pending 6th major extinction and transformation of Earth into a Mars/Venus like state of hibernation (sleep) is consistent with the end of *kalpa* (day) cycle.
One calculation of Kalpa includes a period of 15 Sandhikala (Satya) which is equal to 25.92 * 10^{6} years - very close to calculated periodicity of
extinctions (25.704 * 10^{6} years) which led me to corrections - see calculations in Origin below.
Note that, after I have performed spectral analysis on extinctions, the first dataset I have used gave periodicity of 25.92 * 10^{6}, exactly equal to 15 Sandhikala (Satya).

The same calculation includes a period of 14 Manwantara equal to 4.29408 * 10^{9} years which is equal (up to the 4th decimal) to real age of Earth I have
obtained (4.29409±0.05 * 10^{9} years). This should probably be interpreted as a confirmation that the calculated value is right, making uncertainty much lower
than 0.05 * 10^{9} years, as I understand we should be at the end of the 14th Manwantara period.
Origin
Now that it is clear to me that species of humans have lived on both Mars and Venus (beneath the *imaginary* one, real surface of both should contain the evidence for this),
it is most certain that they have visited Earth.
By Hindus, the Vedas are considered "impersonal, authorless" and "not of a man, superhuman".
Taking that into account along with the fact they are based on knowledge we are just beginning to uncover, the original source is most likely this advanced species of homo.
Literature and at least some philosophy might be local, indigenous to Earth, but numerical values and foundations of principles are not.
Calculations of cycles compared to CR suggests some values might have been misinterpreted from the original source:
- Dwapar and Kali should be the subcycles of Satya and Treta, respectively - not subsequent periods,
- Calculation of Kalpa using multiples of Manwantara and Sandhikala (Satya) is a result of misinterpretation of original data which included extinction periodicity (15 * Satya).

Another interpretation regarding nr. 2 is that we are not at the end of Kalpa, rather at the end of 14 Manwantara period and there should be one more extinction after 15 Satya before the end
of Kalpa cycle. I now believe this is the case.
This leaves only nr. 1 as a possible misinterpretation, but of course, I cannot reject the possibility that I have overlooked something in my calculations.
Assuming that Dwapar and Kali do follow after Satya and Treta, the period between extinctions T_{d} becomes:
$\displaystyle T_d = \left\lfloor {26 * 10^6 \over T_{x_{avg}}} \right\rfloor T_{x_{avg}} = 24 * 1.08 * 10^6 = 25.92 * 10^6\, years$
$\displaystyle T_{x_{avg}} = {{Satya + Treta + Dwapar + Kali} \over 4} = {{1728000 + 1296000 + 864000 + 432000} \over 4} = 1.08 * 10^6\, years$
The T_{d} now becomes exactly 15 Sandhikala (Satya) and age of Earth overestimated by:
$\displaystyle \sigma_{T_{\scriptscriptstyle E}} = \left\lfloor {\Delta T_{\scriptscriptstyle {E_{img}}} \over T_d} \right\rfloor \Delta t_{c_d} + \left\lfloor {\Delta T_{\scriptscriptstyle {E_{img}}} \over T_{x_{avg}}} \right\rfloor \Delta t_{c_x} = 274659276\, years$
giving the real age of Earth:
$\displaystyle \Delta T_{\scriptscriptstyle E} = \Delta T_{\scriptscriptstyle E_{img}} - {\sigma}_{T_{\scriptscriptstyle E}} = 4.265341 \pm 0.05 * 10^9\, years$
Taking into account the uncertainty, this is also in agreement with 14 Manwantara, however the same T_{d} can be obtained with the original assumption (Dwapar/Kali subcycles):
$\displaystyle T_d = 9 * Satya + 8 * Treta = 9 * 1728000 + 8 * 1296000 = 25.92 * 10^6\, years$
According to my revelations, we should be near the end of the existence oscillation period (-64 years max.), so current age of Earth is the integer multiple of this period, for n = 2840, the
age of Earth is:
$\displaystyle \Delta T_{\scriptscriptstyle E} = n T_x = {n \over 2} (Satya + Treta) = 4.29408 * 10^6\, years$
The same result though can be obtained with n = 3976 and T_{x} = T_{xavg} = 1.08 * 10^{6} years.
The period of existence T_{x} is not only the half-life of ^{10}C at scale U^{1}, it is also the half-life of ^{10}Be at scale U^{0}.
In 1987. the half-life of 1.51±0.06 Ma has been measured and
established as standard, but after measurements in 2007. and 2009. a recommended value became 1.385±0.016 * 10^{6} y.
Discrepancy between these values has been explained as due to systematic errors in older measurements. After the correction, the measurement from 1987. yields 1.29 Ma.
Although that value is in agreement with Treta, discrepancy still exists between that value and values obtained with new measurements.
The decay rates should change with a change in space-time structure such as those expected with a pending gravitational collapse/expansion, so if these oscillations are real they should be linked to subtle
changes in gravitational potential, possibly as a precursor to this major change.
If indeed these changes are happening, I would expect them in ^{10}Be and ^{10}C half-life with inverse proportionality.

One might believe the differences in measured ^{10}Be half-life are due to improvements in measurement accuracy, but I have yet to see a proper explanation of the discrepancy with error margins taken into account.
The same problem occurs with nuclear radii and other *constants*. I'd like to see ^{10}Be half-life measured again, if indeed it is changing, it should be even lower by now - so one can put to rest the theory of
absolutely constant decay rates.

Closure
There is some impressive knowledge and philosophy in old scripts. But there is also pointless garbage in some of them.
I would suggest everyone to read Bhagavad Gita though. In fact, I find it more worth than many pointless years I've spent in the, so called, public *school*.
In this state we realize that we are not a physical creature but the Atman, the Self, and thus not separate from God. We see the world not as pieces but whole, and we see that whole as a manifestation of God. Once identified with the Self, we know that although the body will die, we will not die; our awareness of this identity is not ruptured by the death of the physical body. Thus we have realized the essential immortality which is the birthright of every human being. To such a person, the Gita says, death is no more traumatic than taking off an old coat.
