"mouth and a weapon"?
Confucius/Legge: Initiative is here used in the sense of mutually influencing. The magnetic trigram is above and the dynamic trigram is below -- their two influences move, respond and unite with each other. The male is placed below the female -- his repression is her satisfaction and brings fulfillment. Advantage depends upon firm correctness, as in the marrying of a young lady. Heaven and earth stimulate each other and all things attain birth. The sages stimulate the minds of men and harmony is born. If we examine the pattern of these influences, the nature of heaven and earth is revealed.
The second and third sentences in the Confucian commentary elicit the sexual symbolism in this hexagram quite clearly: "The [female] trigram is above and the [male] trigram is below -- their two influences move, respond and unite with each other. The male is placed below the female -- his repression is her satisfaction and brings fulfillment.” Blofeld comments on this in a footnote:
Symbolism works on many levels, and Blofeld's aborted insight does apply to some of them. It is an established fact that the sentences in question accurately describe tantric sexual techniques practiced in the Orient for millennia. To understand the principles of the Work we must be able to see the "obvious" as symbolic of an abstraction -- and vice- versa. Sexual polarity is a very tricky and volatile symbol because we are predisposed to confine it to its most literal meaning. The hardest part of symbolic interpretation is to know where in the continuum a specific symbol belongs in any given situation.I doubt if this should be regarded as shedding light upon the ancient Chinese concept of the most acceptable position for intercourse; it is more likely to mean that the girl is able to depend upon the man as a plant depends upon the earth for its nourishment.
