Metaphysical meaning of rainbow (mbd)
Meta. The "rainbow" as a "token of a covenant between me and the earth" (Gen. 9:13-15) involves the law of obedience (Noah). The rainbow is formed of many drops of water, each of which acts as a prism receiving and transmitting the sunlight. Each drop represents a human being and the whole the race. The seven colors of the solar spectrum are produced by different rates of vibration in a universal energy, which in its myriad activities makes the visible universe.
When man is like Noah, obedient to the guidance of God, he will never be flooded by negative conditions; and when the whole race enters into this obedience the perfect principles will be forever established. The rainbow is a sign of this state in which we all shall form, with our obedient minds, a circle of natural perfection.
