I read somewhere in the past(can't remember where, sorry) that you should cleanse with each full moon and that meant the new moon also.
Each moon is big, round, and full is it not!?!?!?
I have found that over the past two years I have more movement with both moons than in-between moons, I will tell you that the actual full moon is worse than the new moon but both effect me.
So I parasite cleanse twice a month with both full moons. I can tell you with the movement I feel at new moon times they are awake, very alive and on the move...heyjude
