What does it mean that husband is born in darkness and husband is born in invisibility?

Zhuangzi believes that the invisible Tao produces all clear and coherent things, so Tao is also the foundation of things.

Confucius asked Lao Tzu what Tao was. Lao Tzu told him that you should be faithful, dredge your heart, purify your spirit and cut off your wisdom. The road is endless, endless and invisible. How can I make it clear? I can only give you a rough outline.

Zhao Zhao was born in the shadow, Zhao Zhao is knowledge, and shadow is ignorance. "Zhao Zhao" is known, "intangible" is unknown. In Buddhism, "invisibility" is the eighth knowledge, "Aryan knowledge" is "constancy without judgment" and "Zhao Zhao" is the sixth knowledge, which can only play a role through "origin". "Know its white, keep its black" in Tao Te Ching; Knowing his male and guarding his female ",this" male "is" Zhao Zhao "and" female "is" invisible ". Zen Buddhism talks about "breaking words" and breaking the barrier of "knowledge", while Taoists talk about "abandoning saints and wisdom" in order to abandon "visible light" and "invisible". The tangible is born in the intangible, the essence and the spirit are born in the Tao, and the form is born in the essence. Everything in the world is born in the form, in the womb, or in the egg.
