Answer: The King’s palace is not somewhere out there on a mountaintop. This is not the silhouette of a castle, luring us from a distance, or the shape of magical Disneyland.
The palace of the Creator is inside in the human heart, and this is not the picture that a person would want to imagine. It is not pleasant for him to think about how to turn his heart into the palace of the Creator. It immediately requires a person to do something; it forces him to undergo unpleasant states, to take on the laws of bestowal, to change oneself in order to transform himself, his desire, into the temple of the Creator.
