The Sun is the center of third-density existence for this solar system. All the planets and all subsequent life on those planets were born into third density through the Sun. The Sun is a gateway through which higher vibrational energy is transformed into lower vibrational energy and matter, moving downward in vibration and outward in third-density space. The continual flow of energy through the Sun, from higher vibration into third density is what sustains this material existence, including your physical body, which is part of that same consciousness stream.
Black holes are the result of solar ascensions, where the Sun withdraws consciousness from third density back into the higher vibrations, moving inward in third-density space and upward in vibration, transforming matter back into pre-manifest states.
The solar orb, like the nature of man, was divided by the ancient sages into three separate bodies. According to the mystics, there are three suns in each solar system, analogous to the three centers of life in each individual constitution. These are called three lights: the spiritual sun, the intellectual or soular sun, and the material sun (now symbolized in Freemasonry by three candles). The spiritual sun manifests the power of God the Father; the soular sun radiates the life of God the Son; and the material sun is the vehicle of manifestation for God the Holy Spirit. Man's nature was divided by the mystics into three distinct parts: spirit, soul, and body. His physical body was unfolded and vitalized by the material sun; his spiritual nature was illuminated by the spiritual sun; and his intellectual nature was redeemed by the true light of grace — the soular sun. The alignment of these three globes in the heavens was one explanation offered for the peculiar fact that the orbits of the planets are not circular but elliptical.
There is an earthly sun, which is the cause of all heat, and all who are able to see may see the sun; and those who are blind and cannot see him may feel his heat. There is an Eternal Sun, which is the source of all wisdom, and those whose spiritual senses have awakened to life will see that sun and be conscious of His existence; but those who have not attained spiritual consciousness may yet feel His power by an inner faculty which is called Intuition.
What the sun is to the solar system, the spirit is to the bodies of man; for his natures, organs, and functions are as planets surrounding the central life (or sun) and living upon its emanations. The solar power in man is divided into three parts, which are termed the threefold human spirit of man. All three of these spiritual natures are said to be radiant and transcendent; united, they form the Divinity in man. Man's threefold lower nature-- consisting of his physical organism, his emotional nature, and his mental faculties-- reflects the light of his threefold Divinity and bears witness of It in the physical world. Man's three bodies are symbolized by an upright triangle; his threefold spiritual nature by an inverted triangle. These two triangles, when united in the form of a six-pointed star, were called by the Jews "the Star of David," "the Signet of Solomon," and are more commonly known today as "the Star of Zion." These triangles symbolize the spiritual and material universes linked together in the constitution of the human creature, who partakes of both Nature and Divinity. Man's animal nature partakes of the earth; his divine nature of the heavens; his human nature of the mediator.
The Rosicrucians and the Illuminati, describing the angels, archangels, and other celestial creatures, declared that they resembled small suns, being centers of radiant energy surrounded by streamers of Vrilic force. From these outpouring streamers of force is derived the popular belief that angels have wings. These wings are corona-like fans of light, by means of which the celestial creatures propel themselves through the subtle essences of the superphysical worlds.
Some secret orders have taught that the sun was inhabited by a race of creatures with bodies composed of a radiant, spiritual ether not unlike in its constituency the actual glowing ball of the sun itself. The solar heat had no harmful effect upon them, because their organisms were sufficiently refined and sensitized to harmonize with the sun's tremendous vibratory rate. These creatures resemble miniature suns, being a little larger than a dinner plate in size, although some of the more powerful are considerably larger. Their color is the golden white light of the sun, and from them emanate four streamers of Vril. These streamers are often of great length and are in constant motion. A peculiar palpitation is to be noted throughout the structure of the globe and is communicated in the form of ripples to the emanating streamers. The greatest and most luminous of these spheres is the Archangel Michael; and the entire order of solar life, which resemble him and dwell upon the sun, are called by modern Christians "the archangels" or "the spirits of the light.
Sunlight exposure kick starts the pineal gland and stimulates the mind. Any type of light exposure, either directly or indirectly, activates the pineal gland, prompting it to produce serotonin; the neurotransmitter responsible for mood and energy levels. This is why it is crucial to avoid light after the sun goes down, because pineal gland needs to produce melatonin (which is critical for deep sleep) and suppress serotonin. This process can only be accomplished by reducing light from electronics and lightbulbs as much as possible, as the blue light from screens influences the organism to secrete cortisol (stress hormone) which leaves no room for melatonin.
Sunlight also strengthens the aura and makes it much more resistant.
