“A long celebrated ritual period, that the Christians particularly recognize as the time of the resurrection of the son of god. What their illustrious seniors do not explain is that the word Easter comes from the compression of the words eastern and star.
The star that rises or resurrects on the spring equinoctial point is again, the sun itself and not a man. This is why the Jewish feast of the Passover is called Passover. It is because the sun has literally passed over the equinox at Aries, from the winter seasons into the new year.
In fact the feast comes from the Age of Aries, which is why lamb’s blood was smeared on the “doors,” meaning houses of the zodiac. Easter also contains the word aster, again meaning star.”
