Ah,serena!You asked a diplomatic question,indeed confusing to answer.Yes,coincidences occur,many times in our life.Some can be related to the cause of your spells casted,some maybe your fortune and some maybe random.
Magick is mostly,not all,of coincidences but not all coincidences happen because of magick.Confused?Er,my apology,thats how i can answer this question.
like the three Fates of greek mithology? Cloto (spinner), Lachesi (waver) and Atropo (cut the tred of life)..well if you think that so many cultures try to explain what happens to human kind by the means of a divine project or divine intervention you might conclude that the answer can well be yes and/or no..
I suppose you were looking for an answer, instead you find more doubs.
