The Romans sought to control the lands they conquered through unifying their religions and eradicating existing belief systems. In 325CE, the Council of Nicaea decided to hold Easter at this time. Was this significant for the existing Pagan faiths? Yes, of course it was, as the intention was to usurp all pagan holidays and make them Christian ones. This is not a slur on present day Christians, it is simply historically accurate.
We are not humans having a spiritual experience, we are spirits having a human experience. Wakening your spirit, opening that door and becoming truly aware of the world around you and this great Mother Earth, which is home to us all, is incredible.
How beautiful would this great Mother Earth be if we could leave behind ego, and move towards empathy. If we could say to one another, this is my path and whilst it may differ from yours it is of equal value, for to you it is real as to me, mine is real.
If we mindlessly follow dogma, and go through the motions without really searching for our place within this great tapestry, then we are doing no other than joining a club. Learn your prayers and songs, pay your fees and you're in!
