Easter was originally a pagan celebration of the “pregnant” phase of the Goddess Eostar or Eostre, celebrated on the first Sunday after the first full moon after the Spring Equinox. The Moon-hare that was sacred to the Goddess is now know as the Easter Bunny.
Saxon poets apparently knew Eostre was the same Goddess as India’s Great Mother Kali. Beowulf spoke of “Ganges waters, whose flood waves ride down into an unknown sea near Easter’s far home.” Contrary to the west’s idea of her as a purely destructive Goddess, Kali was also the Giver of Life, the fount of every kind of love, which flowed into the world only through her agents on earth, women.
It has been shown that calendar consciousness developed first in women because of their natural menstrual body calendar, correlated with observations of the moon’s phases. Gaelic words for “menstruation” and “calendar” are the same: misact and mioschan. The new-moon sabbaths of ancient Latium were “kalends”, possibly related to the Aryan name of Kali.
Eggs are an ancient symbol of rebirth, which is why Easter eggs, particularly in Russia and Eastern Europe, were usually colored red, the color of life.
