Hence, the heat and light proceeding from our sun cause perpetual spring, and a perpetual vernal warmth inspires those with whom love is united with wisdom in just proportion; and our Lord, by the eternal union of heat and light, breathes nothing but uses: hence also come the Germinations of your earth, and the connubial associations of your birds and animals in the spring; for the vernal warmth opens their interiors even to the inmost, which are called their souls, and affects them, and communicates to them its conjugial principle, and causes their principle of prolification to come into its delights, in consequence of a continual tendency to produce fruits of use, which use is the propagation of their kind.
"The Delights of Wisdom Pertaining to Conjugial Love"
Emanuel Swedenborg
Dry-farmers try to provide against this danger by using an unusually large amount of seed, assuming that a certain amount will fail to come up because of the repeated partial Germinations.
