And Jesus answered and spake unto them again by parables, and said, the kingdom of heaven is like unto a certain king, which made a marriage for his son, and sent forth his servants to call them that were bidden to the wedding and they would not come.
Again, he sent forth other servants, saying, Tell them which are bidden, Behold, I have prepared my dinner my oxen and my fatlings are killed, and all things are ready come unto the marriage.
But they made light of it, and went their ways, one to his farm, another to his merchandise.
And the remnant took his servants, and entreated them spitefully, and slew them.
But when the king heard thereof, he was wroth: and he sent forth his armies, and destroyed those murderers, and burned up their city.
Then saith he to his servants, The wedding is ready, but they which were bidden were not worthy.
Go ye therefore into the highways, and as many as ye shall find, bid to the marriage.
So those servants went out into the highways, and gathered together all as many as they found, both bad and good: and the wedding was furnished with guests.
And when the king came in to see the guests, he saw there a man which had not on a wedding garment.
And he saith unto him, Friend, how camest thou in hither not having a wedding garment? And he was speechless.
Then said the king to his servants, Bind him hand and foot, and take him away, and cast him into outer darkness; there shall be weeping and gnashing of teeth.
For many are called, but few are chosen.
— Matt. 22:1-14
In this parable lies hidden one of the most significant of occult truths: the mystic marriage of the lower self to the Higher Self, the ultimate goal for every spiritual aspirant.
Reaching this coveted goal involves the activities of two important glands in the head: the pituitary body and the pineal gland. Between these two glands lies the third ventricle, called by occultists the "marriage bed." The persistent endeavor to live purely and unselfishly establishes a current of spiritual force in the spinal canal, and when the aspirant has sufficient of this, and is considered worthy to receive esoteric instruction, he is taught exercises which set the pituitary body in motion. The lines of force thus established are continued until they reach the pineal gland and the gap between the two is bridged. From the time this bridge is built, or the wedding performed, man becomes clairvoyant and able to direct his spiritual gaze at will.
Since the coming of the Christ as the indwelling Planetary Spirit of the Earth, "whomsoever will" has been bidden to the mystic wedding, but many there will be who cannot attend because of having "made light of" living the life which would insure them admittance. Continuing in their earthly, sense life, they will possess no wedding garment, or soul body, and therefore when the time of evolutionary change comes they will be cast "into outer darkness," or left behind to take up their pilgrimage later with another stream of life.
The few who are "chosen" will be those who,
regardless of their station in life, by their own efforts to emulate
the ministering Spirit of Christ Jesus in their daily lives have attracted
sufficient of the light and reflecting ethers to form the holy wedding garment,
the luminous vesture which is the blessed symbol of the Christ Within.
