Perception of Knowledge in Chinese / Japanese...

知識 has the very strong meaning of “knowledge” and, in some contexts, “learning.”

The first character represents “to know” or “to realize.”

The second character alone refers to the ability to “recognize” or “realize” and can also be used to mean “knowing.”

知 means realization or true knowing.

This can also translate as to know, to be aware, wisdom, or higher knowledge.

From older Buddhist ideas, this can represent विद्या (Vidyā or Vidya) or ज्ञान (Jñāna or Jnana) and even the combination Sanskrit word विज्ञान (Vijñāna or Vijnana) which can translate as wisdom arising from perception or knowing.

However, 知 should be distinguished as true knowing versus having a relative understanding or 會.

身心 means “body and mind” or “mental and physical” in Chinese and Japanese.

In the Buddhist context, body and mind encompass the five elements (skandha) of a sentient being.
The body is the physical material (rūpa) of life. The mind embraces the other four skandhas, which are consciousness, perception, action, and knowledge.
