Bhagavad Gita Verse 2.69

सम्पूर्ण प्राणियोंके लिये जो रात्रिके समान है, उस नित्य ज्ञानस्वरूप परमानन्दकी प्राप्तिमें स्थितप्रज्ञ योगी जागता है और जिस नाशवान् सांसारिक सुखकी प्राप्तिमें सब प्राणी जागते हैं, परमात्मा तत्त्वको जाननेवाले मुनिके लिये वह रात्रिके समान है|

When it is night for all others, the wise man is always awake. When others are aware and deceived (deluded) by sensual objects, the wise man who knows the truth and has realized God, shuts his eyes to daylight and the misleading material objects that attract people, and considers it night. He is not easily deceived.
