In Cancer, God breathed into man's nostrils the breath of life and man became a living soul. In those words you have established the relation which exists in the mind of God between spirit (the breath of life), the soul (consciousness) and the human being (the form). As a human being passes around and around the zodiac in the ordinary manner, he continually and consciously enters into life in Cancer, the constellation under which the Law of Rebirth is applied and administered. It is not desire, basically, which prompts return. The main incentive is sacrifice and service to those lesser lives that are dependent upon the higher aspiration (which the spiritual soul can give) and the determination that they too may attain planetary status equivalent to that of the sacrificing soul. The point of greatest interest lies in the fact that it is group rebirth which is taking place all the time and that the incarnation of one individual is only incidental to this greater happening.
The task in Cancer is to use the available energy flow to release the soul principle imprisoned in all material form. Form is necessary for manifestation but matter can and must provide a vehicle for the soul to use. Energy in this sign can be directed in meditation towards building the "new materialism", defined as the right use and development of all the material resources of the planet for the welfare and progress of the whole human race. The light and energy of the soul must be released and turned towards this goal.
