Cassiel (HebrewקפציאלQafsielKaziel) is the Latin name of an archangel in post-biblical Judeo-Christian religion, particularly that of the Kabbalah. Unlike many other angels, Cassiel is known for simply watching the events of the cosmos unfold with little interference. He is the angel of solitude and tears, and is said to preside over the deaths of kings.
He is often included in lists as being one of the seven archangels and often associated with the Seventh Heaven.
In the magical text Berit Menuchah, Cassiel is associated with Kefitzat Haderech, the ability to travel quickly through space. Magic spells using his name are cast to create destruction, to scatter crowds, to cause a person to wander aimlessly, or to fall from a position of power.
Ancient Hebrew amulets bearing his name are used to drive away one's enemies. The words on the charm are written with the blood of a bird and then tied to the foot of a dove. The dove is then set to flight, taking one's enemy with it. Should the bird refuse to fly, it is a sign that one's enemies won't depart either.
Archangel Cassiel can also be called: Casiel, Cassiel, Castiel, Mocoton, Kafziel, Qafsiel, Qaphsiel, Qaspiel, Quaphsiel. He is also known as the angel of temperance.
In the Jewish Kabbalah
In rabbinic literature, the Kabbalah is the only one that relates the identity of angels with the souls. There are a few different views on how many classes of angels there actually are. One of the older views, the most widely known view, consists of angels being divided into seven classes. This allows the number of archangels connect to the heavens. Another view states that there are only three true archangels due to the fact that there are only three heavens. This view states that the number of heavens corresponds with the number of angels. When these two are combined, you come up with a third view that states that there are ten classes of angels. Another theory pertains to the names of the archangels to the planets. Archangels are also referred to as the "chief angels" and called the "angels of the presence."
Archangels are connected to a level of sephiroth, the Kabbalah contains 10 levels of sephiroth each holding different meanings and responsibilities. Each sephiroth is assigned a name and a number and becomes associate with an archangel, a name of God, an angelic order, and a planetary force. These levels are sometimes referred to as Vessels of Light because they are representative of the progression of the realms in which they are connected. The sephiroth are God's means of interacting with the physical world.
