I don't feel guily. Ive never really had this contemporary urge either to "declutter". My house is full of things I like, things which have special memories for me. tarot is just one category of things which I have a lot of, and it is the one we discuss here. But when people come into my house, they don't notice the tarot decks (which are stuffed on shelves or in boxes). I have lots of other objects. Lots of porcelain things, lots of antique paperweights etc. I have a couple of cabinets full of curiosities, fragments of statues, religious artefacts, things Ive bought from flea markets all over the place since I was young. People come into my house and notice all this first, but people here think I have a lot of decks because it is what we talk about here
And I don't get out and "use" all the other stuff either. However, if I have a night in and I sit cross legged on the floor and go through decks just looking at them, this to me is "using" them.
Reading is one use. Looking at them is another. Thinking about them later in the day when Im out and about is another use... These decks - whether with me or not - enrich my days.
I am sometimes struck by how many decks I have which I really love, and wouldn't it be nice to have more hours at home to be able to enjoy them, but I don't feel guilty, no.
Do other people feel guilty about spending too much on their mobile phone? I guess not...
Feeling guilty is a product of the whole feng shui culture, that somehow your energies are going to be blocked if you don't get rid of stuff and you will be unhappy. Silly. I mean, honestly...
