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.

When you meet a wise person, you should learn from them and be inspired to become as wise as they are.

見賢思齊 is a pretty long proverb in English, but in Chinese, it's only four characters.
However, in Chinese, the deeper meaning often surpasses the dictionary definition of each character.

In this case, you should seek wise people to learn from throughout your life...
Always try to learn enough to become equal to them. It also suggests that learning and seeking wisdom is a non-ending cycle.

覺 can mean to feel; to figure out; thinking; awake; aware; bodhi; knowing; understanding; enlightenment; illumination; apprehend; perceive; realize.

覺 is a character that is impossible to define in a single word.

This term is often associated with Buddhism where it's understood to be: Illumination, enlightenment, or awakening in regard to the real in contrast to the seeming. However, it can also refer to enlightenment in regard to morality and evil.

Notes:

In Japanese, this can be the personal name Satoru.

In certain context, and only when pronounced as “jiao” in Chinese, it can refer to a nap, sleep or the state of sleeping. However, as a single character on a wall scroll, everyone will read this with the awareness or enlightenment context.

By no means is this the only way to write enlightenment. In fact, you should only choose this character if you are looking more for a word meaning awareness.

慧 is a single character that can mean wisdom but it has more of an “intelligent” flavor. This can also mean cleverness or wit.
