(6) “That which is born of the flesh is flesh: and that which is born of the spirit is spirit. (7) “Marvel not that I said unto thee, Ye must be born again. (8) “The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh and whither it goeth; so is everyone that is born of the spirit.” To be born of water means simply to be born from the mother’s womb. To be born of the spirit means to be born from the fructifying breath of the wind; this we learn from the Greek text (where spirit and wind are expressed by the same word, πνεῦμα) τὸ γεγεννημένον ἐκ τῆς σαρκος σάρξ ἐστιν, καὶ τὸ γεγεννημένον ἐκ τοῦ πνεύματος πνεῦμά ἐστιν.—Τὸ πνεῦμα ὅπου θέλει πνεῖ,[455] etc. This symbolism rose from the same need as that which produced the Egyptian legend of the vultures, the mother symbol. They were only females and were fertilized by the wind. One recognizes very clearly the ethical demand as the foundation of these mythologic assertions: _thou must say of the mother that she was not impregnated by a mortal in the ordinary way, but by a spiritual being in an unusual manner_. This demand stands in strict opposition to the real truth; therefore, the myth is a fitting solution. One can say it was a hero who died and was born again in a remarkable manner, and in this way attained immortality. The need which this demand asserts is evidently a prohibition against a definite phantasy concerning the mother. A son may naturally think that a father has generated him in a carnal way, but not that he himself impregnated the mother and so caused himself to be born again into renewed youth. This incestuous phantasy which for some reason possesses an extraordinary strength,[456] and, therefore, appears as a compulsory wish, is repressed and, conforming to the above demand, under certain conditions, expresses itself again, symbolically, concerning the problem of birth, or rather concerning individual rebirth from the mother. In Jesus’s challenge to Nicodemus we clearly recognize this tendency: “Think not carnally or thou art carnal, but think symbolically, then art thou spirit.” It is evident how extremely educative and developing this compulsion toward symbolism can be. Nicodemus would remain fixed in low commonplaces if he did not succeed in raising himself through symbols above this repressed incestuous desire. As a righteous philistine of culture, he probably was not very anxious for this effort, because men seem really to remain satisfied in repressing the incestuous libido, and at best to express it by some modest religious exercises. Yet it seems to be important, on the other side, that man should not merely renounce and repress and thereby remain firmly fixed in the incestuous bond, but that he should redeem those dynamic forces which lie bound up in incest, in order to fulfil himself. For man needs his whole libido, to fill out the boundaries of his personality, and then, for the first time, he is
