Hi Janssen,
Guilt is a mind-made concept. Your mind has a few tools in its arsenal, like fear, comparison, etc., and guilt is another one of those that makes you worry about “being a traitor” to your own religion. In reality, a religion’s job is just to put you on the path to freedom – you shouldn’t feel trapped by it! So if you’re resonating with Buddhism (or any -ism) that doesn’t make you feel trapped, but instead makes you feel free, that’s a good thing! And you don’t really have to convert to become a Buddhist – you just have to be open to who you really are, that’s all!
