醉心不醉人
[zuì xīn bù zuì rén]
Translates as 'Dazed at Heart but Not Drunk Physically.' This may indicate someone who gets completely engrossed or fascinated emotionally, intellectually, yet maintaining physical sobriety. Perhaps reflecting a state where they are intensely passionate about an ideal or concept, keeping the literal drunkenness aside and highlighting the power of inner intoxication over bodily reactions.
