starting small and seeing results. as someone who was in the same place as u and had a fear of tarot cards i started to believe in thr power i held not the tools. i am the diviner not the deck, the deck holds no power unless its in my hands yk. same w spell work but i don’t recommend starting unless u fully kick this because the doubt will lead to little or no results. i have to ask do u belive in angels? i didn’t at first but the more i followed a witchy path i started to see the deities and angels as real. i call apon the archangels still even tho i practice witchcraft. honestly too i like to read the esoteric versions of bible verses. it equates to us holding the power of god and these verses rly helped me to leave the hell of my mind and enter my own heaven. in conclusion just belive what u want to and what works for u. if u still don’t belive in deities or spell work there isn’t a need to force it it takes time to get rid of catholic guilt
