All I want to know is why does King of Heart mean House in Lenormand? It is different from other system?
The King of Hearts is the second layer, adding an extra dimension to the meaning.
The House is portraying creation, life, and you. It speaks of nurturing, psychic energy, a Transmission of the Divine into a life-form called Beta. The House called Sojouin, maga, Magh- magos (Sanskrit), and the exact translation is Priest of the Sun, the unification of gamAgamakArin within you, with the PowerPoint (Bindu), the cosmic centre.
The King of Hearts is the second layer of the card of the House:
Consciousness is assured by the King of Hearts, by stabilising the Physical Plane, Heaven or Consciousness of the Divine Mind.
