this kind of interpretation follows the hindu cyclical theory (which is true of course) but you can't just transpose it to the zodiac

cycles come in Great Years of 13000 years, equal to half a precession of the earth's axis, according to 4:3:2:1, 1 being the length of the kali yuga

to know what astrological age we were in when the current manu cycle started (130.000 years) we need to know what sign the axis was in then (assuming you can attribute that sign as closest to the source)
by my calculations that would be the cancer sign

however as the earth axis goes through all twelve signs every cycle (except kali cycle then it does 6) I maintain that you cannot transpose signs to the hindu doctrine of cycles and closeness to the source
gpt
and an argument to strengthen this is that the axis rotates counterclockwise in time, so if the yuga started at Aries the next age would be Pisces.

Unless the movement of the axis has not been constant, I grant you that
