Maon (מִעוּן): The fourth Heaven is ruled by the Archangel Michael, and according to Talmud Hagiga 12, it contains the heavenly Jerusalem, the Temple, and the Altar. Makon (מִכּוּן, Makhon): The fifth Heaven is under the administration of Samael.
The Fourth Heaven contains the heavenly city of Jerusalem. Also the location of the Garden of Eden
In the Book of Ezekiel in the Hebrew Bible, New Jerusalem, or “[where] YHWH [is] there”) is Ezekiel’s prophetic vision of a city centered on the rebuilt Holy Temple, the Third Temple, to be established in Jerusalem, which would be the capital of the Messianic Kingdom, the meeting place of the twelve tribes of Israel, during the Messianic era. The prophecy is recorded by Ezekiel as having been received on Yom Kippur of the year 3372 of the Hebrew calendar. It will be inhabited by people to live eternally in spirit form, created by God as a gift to mankind. Not everyone will reside in New Jerusalem, as most will possibly stay on Earth.
In the Book of Revelation in the New Testament, the city is also called the Heavenly Jerusalem, as well as being called Zion in other books of the Christian Bible.
The fourth heaven, Machon, by his angels leads the sun by day, and through other angels by night. The chief angel is called Michael.
Fourth heaven contains the course of the sun and the moon.
The dynamics of the Sun operates in the Fourth heaven, as it passes through two sets of twelve Sun gates, both East and West. These solar dynamics have influence on the earth and moon. The Sun gates represent the twelve constellation signs of the zodiac. This heaven also introduces the elements of the sun known as the Phoenixes and Chalkydri.
Most varied in character, perhaps, of all the heavens is the fourth, for here the powers of the most advanced souls find their exercise, so far as they can be expressed in the world of form. Here the kings of art and of literature are found, exercising all their powers of form, of colour, of harmony, and building greater faculties with which to be reborn when they return to earth. Noblest music, ravishing beyond description, peals forth from the mightiest monarchs of harmony that the earth has known, as Beethoven, no longer deaf, pours out his imperial soul in strains of unexampled beauty, making even the heaven world more melodious as he draws down harmonies from higher spheres, and sends them thrilling through the heavenly places. Here also we find the masters of painting and of sculpture, learning new hues of colour, new curves of undreamed beauty.
And here also are others who failed, though greatly aspiring, and who are here transmuting longings into powers, and dreams into faculties, that shall be theirs in another life. Searchers into Nature are here, and they are learning her hidden secrets; before their eyes are unrolling systems of worlds with all their hidden mechanism, woven series of workings of unimaginable delicacy and complexity; they shall return to earth as great “discoverers,” with unerring intuitions of the mysterious ways of Nature.
In this heaven also are found students of the deeper knowledge, the eager, reverent pupils who sought the Teachers of the race, who longed to find a Teacher, and patiently worked at all that had been given out by some one of the great spiritual Masters who have taught humanity. Here their longings find their fruition, and Those they sought, apparently in vain, are now their instructors; the eager souls drink in the heavenly wisdom, and swift their growth and progress as they sit at their Master’s feet. As teachers and as light-bringers shall they be born again on earth, born with the birthmark of the teacher’s high office upon them.
Many a student on earth, all unknowing of these subtler workings, is preparing himself a place in this fourth heaven, as he bends with a real devotion over the pages of some teacher of genius, over the teachings of some advanced soul. He is forming a link between himself and the teacher he loves and reverences, and in the heaven-world that soul-tie will assert itself, and draw together into communion the souls it links. As the sun pours down its rays into many rooms, and each room has all it can contain of the solar beams, so in the heaven-world do these great souls shine into hundreds of mental images of themselves created by their pupils, fill them with life, with their own essence, so that each student has his master to teach him and yet shuts out none other from his aid.
