A blind snake shows no fear.
Literal
Blind-snake [topic-には] not-afraid.
A proverb meaning that ignorance brings fearlessness — someone who doesn't understand the danger of a situation won't be afraid of it. The classical negative 怖じず (from 怖じる 'to fear') uses the literary ~ず ending still active in proverbs and elevated prose. 盲 ('blind') paired with ヘビ ('snake') — written in katakana here instead of the kanji 蛇. The には marks the snake as the contrasted topic.
