Nirayana system

[Guest guest]

Dear Group mmbers..

"The entir zodiac system slips backward i.e from the east to west

with respect to the constellation at the rat of of about 50 degre 3

minute of an arc of the eclipt pr year. This shift is calld the

precession of the quinox. the year in which th precession of the

equinox was zero is considered zro qnyqnamsa year and total

accumalted displacement for th year of th birth and is subtracted

from the obsrvd longitude of planets. in sanskrit the NIRAYANA mean

without ayama."

Now I want to ask why the entir system slips backward any reason???

Also what is the difference in kp ayanams and vedic astrologr's

anayamsa.................

Thanxs and rgards
