The thing about having collections of things is that it (mostly) doesn't matter what you have. It does matter if a thing is useful or isn't, a thing is pretty or isn't, but the more minute distinctions aren't as important as capitalism wants us to believe. We have bought IN.
In the end, if you're a card reader, it doesn't matter what deck you have in your hands, you'll be able to read them. You are the vessel. You could have 47 tarot decks, 470, or just 1 and the message would be the same as long as you feel some level of connection to the imagery.
I don't need a "connection" to the imagery in more than probably 10? 15? 20? tarot decks. I'm down to <20 in the Great Culling of 2021. I spent most of 2019 and 2020 acquiring soooo many decks of cards. Seeing how different artists portray the ideas within the tarot system is useful to learning tarot, but I don't need to OWN the decks to do this.
I am learning to be happy with what I have and to resist the temptation to keep buying more and more things I don't need, but this is a difficult and multilayered process.
The things you have don't really matter all that much. I've spent so much of my adult life thinking really fucking hard about the acquisition of the "perfect" object. In some cases, it works to my advantage, but in many others it serves only to disappoint me when nothing is perfect, because nothing can be perfect.
Accept flaws in items you've already acquired. Acquire items because they're pretty, useful, and available to you (affordable, physically THERE, etc). You'll never find the "perfect" tarot deck. You might find several you love and use regularly, but they won't be perfect. NONE of them.
Acceptance of the tools you have available to you is the key. At least, that's what I'm thinking today.
