The word Melchizedek is an ancient signature that has to do with the primal coding of the Sound and Light Fields that this particular 15-dimensional time matrix was formed on. So when we say Melchizedek, The Holy Order of the Yunasai, or the Melchizedek Cloister, it's like a family name way up all of the levels of the consciousness in this time matrix.
Melchizedek is actually a translation of the vibrational pattern of the collective of consciousness; the Cosmic Family of Consciousness that seeded the hominid forms.
The flash-line sequences, the scalar arrangements have a sound translation when they are brought down the dimensional scale into Light-Sound Scalar Waves. When you translate those flash-line sequences through the English language flash-line sequences you come out with the Sound-Tone "Melchizedek."
The people in this Time Matrix came out of the collective that was called the Melchizedek collective. The Melchizedek Cloister - the word "cloister" got put on it to make a distinction when some of those that had fallen from that collective went and took the teachings and twisted them.
All humans are connected to the Melchizedek God Seed, although there are some beings currently in human bodies that originally came from other God Seeds. Because the Melchizedek God Seed is one of the God Seeds that has held the integrity of most of its family lines intact, representatives of this line exist on the cosmic and other levels of being as the Melchizedek Priesthood.
The human lineage is directly descended from this God Seed, and originated to address the problem of monadic reversal, which occurs when consciousness in the time matrix gets disconnected from its monadic level of being. (Keylontic)
