Bhagavad Gita Verse 13.18

वह परब्रह्म ज्योतियोंका भी ज्योति एवं मायासे अत्यन्त परे कहा जाता है । वह परमात्मा बोधस्वरूप, जाननेके योग्य एवं तत्त्वज्ञानसे प्राप्त करनेयोग्य है और सबके हृदयमें विशेषरूपसे स्थित है|

He is light of all lights and is said to be beyond darkness. He is Knowledge, the Knowable (that which has to be known) and the goal of Knowledge, and He is seated in the hearts of all.
