I have pulled a card to understand logion 8 from the Gospel of Thomas.
(8) And he said, "The man is like a wise fisherman who cast his net into the sea and drew it up from the sea full of small fish. Among them the wise fisherman found a fine large fish. He threw all the small fish back into the sea and chose the large fish without difficulty. Whoever has ears to hear, let him hear."
I have pulled Seven of Cups from the Spirit of Flowers Tarot as an answer and I cannot make anything much of it, I cannot find a ´deep´ or ´hidden´ meaning.
If this boy has chosen the big fish he has made a good choice for he is well-fed, looks happy and satisfied. The image on this card is very different from the RWS Seven of Cups on which a man needs to choose, but is delusional, caught up in dreams and does know what to choose.
What is the hidden meaning of the words of this logion? What I can find is not so hidden. It think the meaning is that it is important to choose well, it makes one happy and satisfied.
But probably the tarot gave me this card -which do not really understand- because ´behind´ the card in the tradition is the illusional Seven of Cups of the RWS. Probably asking for a hidden meaning is asking for an not-understanding, for an illusion.
