Horus...

After reading about Horus and the tree of life in Malkuth I am really convinced either I lived in Egypt in my earlier lifetime or my Guide/Master is very fond of Egyptian religion. So many of my experiences end up being related to Egypt. Horus is one of the most ancient deities of the Ancient Egyptian religion, who appears in his earliest form in late Predynastic Egypt.He was usually represented as a man with a falcon's head.
He is called the God of Sky and sometimes God of Sun This is thought to be the original form of Horus. His name meaning 'high' or 'distant' reflects his sky nature. He was seen as a great falcon with outstretched wings whose right eye was the sun and the left one was the moon.Eye of Horus symbolic of indestructibility and is symbolic of rebirth. It is a powerful symbol of protection, and it is also considered to confer wisdom, health and prosperity.

Malkuth:

Malkuth is the first sphere upon which an initiate enters the Tree of Life. It is in this realm that you learn of the existence of other things, other than the earth, and touch upon divine sources. Sandalphon is the name of the Archangel that presides over this sphere and without his permission, you will not be allowed to leave Malkuth and enter into the other spheres of the Tree of Life. Newcomers to the Tree of Life will spend some time exploring in this sphere, some of that time on his or her own. Eventually, when Sandalphon feels the time is right and you have proved to him that you are ready and worthy and pure of heart enough to enter into the other realms, he will come up to you and present you some kind of key. This key is a symbol that you can travel to the other spheres.Now there are also three other places that are technically a part of Malkuth. They actually are located midway up the tunnels (or paths) that lead away from Malkuth and into the rest of the Tree of Life, but often the initiate is sent on journeys to these places by Sandalphon to prove his/her worth; so we will mention them here.
The first place is located in the North-East corner of Malkuth. And it is the "Towers of Dark and Light."The second place is located in the North-West corner of Malkuth. It is a similar place in feel and appearance, to the Towers, and it usually is marked by two huge pillars of dark and light. This is the palace of judgment.The third place is directly North in Malkuth, and it is the Crystal Palace. The way to this place is through a crystal garden with a crystal road. You might meet the crystal princess here.It is here that you get gifts of energy and of special skills that are dormant within you that just need to be awakened. Sandalphon (in one of his forms,In his traditional female form, he will look like a beautiful ice princess or crystal princess. ) will usually be here and he will guide you to where you need to be in the palace and to what you

will receive.

Wow, so finally after hours of research I have zeroed upon the place which I saw. I still don't know whether this place is associated with tree of life in Egyptian religion or with Kabbalah. I found this word Malkuth mentioned in both places. I didn't meet any crystal princess or anyone else there though.
