Chapter XLII reminds me of the idea that there is polarity in all things. Not so much as seeing the world in black or white, but that there is black and white in all things, and that corresponds to sex, ie, that dark and night and yielding is female while the white and day and force is male. But the fact is, that you need both to maintain balance.
Although, one random thought that I always had was, if everything is polar like this, what are creatures like amoebas? They’re asexual and reproduce from themselves. It’s too bad we couldn’t get that perspective. But I assume they don’t have much of a perspective about anything, seeing as they’re unicellular and all.
The Tao gives birth to One.
One gives birth to Two.
Two gives birth to Three.
Three gives birth to all things.
All things have their backs to the female
and stand facing the male.
When male and female combine,
all things achieve harmony.
Ordinary men hate solitude.
But the Master makes use of it,
embracing his aloneness, realizing
he is one with the whole universe.
