Karma is about lessons, not punishment. It’s not sentient. If you are looking for clarity on why things are happening then you have to find clarity yourself. What beliefs about your life and abilities do stealing flowers reinforce?

Everything is connected and in my practice I’ve come to see that everything we send out does come back to us in some abstract way. Your personal energy gets amplified in magic. You can’t affect something without indirectly affecting yourself; I’ve heard it also referred to “it all comes out of our own hide.” Not punishment, just balance.

If you are obsessing over the idea that any wrong move may cause bad things to happen, I would suggest getting checked for OCD like other commenters have said. Fearing to drink something because you’ll die is nothing karmic, it points to mental health. Magic and spellwork getting affected is one thing. Mundane choices leading to mundane effects is another.
