Can I have a meaningful spiritual practi

Yes. Nothing in tarot requires belief in a god.

The deck is a picture system with 78 images, and the Major Arcana are archetypes — The Fool, The Hermit, The Tower, The World — not beings to pray to. You can read a spread as a way of putting a question into a shape that forces you to say what you actually think. That's most of what the practice is doing anyway.

What it honestly is without belief: a structured mirror plus a check. You name a real situation, a deck gives you images that don't know anything about your life, and the meaning arrives from *your* reading of them. The value is in the sorting — past / present / next, or situation / obstacle / advice — not in the cards having information. Cards cannot tell you what your boss will do next quarter; they can only make you articulate a position you were already avoiding, which you can then verify against the actual document, the actual person, the actual record.

If you want it to stay honest, keep two rules: the reading ends in something you can go check in the world, and you never use a card to settle a medical, legal, financial, or life-or-death question. Those go to a doctor, a lawyer, a licensed adviser, or — for immediate danger — whoever can be reached right now.

Practice that works without belief is small: one card, one question you actually have this week, and one action you could take today. If you'd like, tell me a question that's live for you and I'll draw for it properly.
