眼见心不净
[yăn jiàn xīn bù jìng]
The literal translation is 'eyes see, heart is not clean.' It suggests that what one sees can taint or trouble their mind, meaning that the external world's influences have affected the inner peace or purity of this person. This username might indicate a feeling of being disillusioned or finding it hard to maintain one's integrity amidst the realities of life.
