Sorry for the late reply I've been stuck in a reddit binge before Apollo dies. Anyway, every tarot practitioner views it differently. For me, it's a way to connect with myself and the energies around me. It's very grounding since it's just another tool for me to assess my actions and possible outcomes. It's not something that predicts your future per se. I avoid personal bias by evaluating whether the reading resonates with what I feel and what is objectively happening around me.

In a nutshell, it's a bunch of cards (78 cards) with different symbolisms and meanings. Pull as many as you need, interpret it based on the basic symbolisms and key words on your guide. Decide whether it resonates or not. Do it again as you please. It's hard at first since there are a lot of cards but it just takes some practice to get better as with any other thing. Sometimes it takes me weeks before I grab my cards again, sometimes I need it on the daily.
