What is another word for gnosis?

Could you please enlighten me on an alternative term that could be used in place of "gnosis"? I'm seeking a synonym that conveys a similar meaning, perhaps one that is more widely recognized or fits better within a particular context. Is there a word that encapsulates the essence of gnosis, which often refers to the act of knowing or understanding something through intuition or insight? I'm curious to learn if there's a term that resonates similarly with the concept of gaining profound knowledge or insight.
