This is the vital fluid emanated from any planet, which constitutes its basic coloring or quality, and is produced by a repetition within the planet of the same process [92] which is undergone in connection with man and solar prana. The planet (the Earth, or any other planet) absorbs solar prana, assimilates, what is required, and radiates off that which is not essential to its well-being in the form of planetary radiation. Planetary prana, therefore, is solar prana which has passed throughout the planet, has circulated through the planetary etheric body, has been transmitted to the dense physical planet, and has been cast off thence in the form of a radiation of the same essential character as solar prana, plus the individual and distinctive quality of the particular planet concerned. This again repeats the process undergone in the human body. The physical radiations of men differ according to the quality of their physical bodies. So it is with a planet.

1. Solar devas, who transmit the vital fluid which circulates in the etheric body.
2. Planetary devas of a violet color, who are allied to man's etheric body, and who transmit earth's prana, or the prana of whichever planet man may be functioning upon during a physical incarnation.

A very pertinent question might here be asked, and though we may not fully explain the mystery, a few [93] suggestive hints may be possible. We might ask: What causes the apparent deadness of the Moon? Is there deva life upon it? Does solar prana have no effect there? What constitutes the difference between the apparently dead Moon, and a live planet, such as the Earth ? (S. D., I, 170-180.)

Here we touch upon a hidden mystery, of which the solution lies revealed for those who seek, in the fact that human beings and certain groups of devas are no longer found upon the Moon. Man has not ceased to exist upon the Moon because it is dead and cannot therefore support his life, but the Moon is dead because man and these deva groups have been removed from off its surface, and from its sphere of influence. (S. D., I, 179.) Man and the devas act on every planet as intermediaries, or as transmitting agencies. Where they are not found, then certain great activities become impossible, and disintegration sets in. The reason for this removal lies in the cosmic Law of Cause and Effect, or cosmic karma, and in the composite, yet individual, history of that one of the Heavenly Men Whose body, the Moon or any other dead planet at any time happened to be.
