The Alchemy of JK Rowling

Chapter 59 - Kreacher

I see 12 Grimmauld Place as the Master Alchemist’s old physical body which can be used for a few years in the service of the Masters of Compassion (‘The Order of the Phoenix’) to help humanity. The Master himself is no longer dependent on this body, and has a new etheric and a new astral body. However something has to keep this ‘old house’ alive. It is the etheric body which gives life to the physical body. In Harry Potter this is symbolised by making the etheric body a house elf, which serves the owners of a house. Harry as the new soul has released the etheric body from its attachment to the physical body (Narcissa and Lucius). Dobby now serves the new soul.

However what keeps the ‘old house’ going? The new etheric body cannot do this. The forces from the Universe of God, or the Kingdom of Heaven, or the Sixth Cosmic Plane, are of an extremely high vibration, and they would cause the immediate death of the physical body if they entered it. That would be like pouring molten iron into a glass jar. It would immediately shatter into a thousand pieces. So what happens is that there always remains a steady but minimal flow of natural etheric substance from the seventh cosmic plane to provide for the needs of the old physical body.

This explains why Kreacher went to Narcissa, another symbol for the physical body. That’s what Kreacher symbolises - the minimal remnant of the etheric body necessary to keep ‘the old house’ functioning.

In Part 7 this old etheric body plays a very sympathetic role. Harry is very kind to Kreacher and restores his dignity. The New Soul will take care of the old personality and if we entrust ourselves to Him we will never lack anything.
