Whoa this is informative and inspiring to me! I have never studied Tarot, but am learning little bits from friends like you and Reinhard here on steemit. I did not know there were so many cards that depicted dualities before reading this post.

From my very novice perspective I have no knowledge of why the pentacles card would imply hierarchy whereas the other cards portray more equality. So I can only attempt to answer your question intuitively. For me the pentacles image reflects movement and dance. everything constantly changes. There is truly never any stillness in this ever expanding universe buzzing with energy. So, her dancing reflects this in that sometimes one way (one hand/pentagram) will seem better or higher, and then the dance will change and the opposite way will appear the greater way. But really they are equal and not separate.

Thank you for resteeming my post, crediting my post with inspiring this one 🙌🏽🙏🏽, and for pointing my attention to it.
