Letters 73.16

Do you marvel that man goes to the gods? God comes to men; nay, he comes nearer,—he comes into men. No mind that has not God, is good. Divine seeds are scattered throughout our mortal bodies; if a good husbandman receives them, they spring up in the likeness of their source and of a parity with those from which they came. If, however, the husbandman be bad, like a barren or marshy soil, he kills the seeds, and causes tares to grow up instead of wheat. Farewell.
