I wanted an image in order to understand the sentence: “(Rather) the kingdom is inside of you, and it is outside of you.” The card I received as an answer is Six of Pentacles from the Tarot of White Cats.
One of the themes of the Six of Pentacles is sharing. I think you need to experience the kingdom on the inside to be able to share it. You need to feel rich. Related to this is that you need to know the kingdom inside in order to be able to recognize it.
