Śrīmad-Bhāgavatam
[Canto 8, Ch. 5]
intelligence, is working under His control. He is the illuminator of everything and has no ignorance. He does not have a material body subject to the reactions of previous activities, and He is free from the ignorance of partiality and materialistic education. I therefore take shelter of the lotus feet of the Supreme Lord, who is eternal, all-pervading and as great as the sky and who appears with six opulences in three yugas [Satya, Tretā and Dvāpara].
PURPORT
In the beginning of  Śrīmad-Bhāgavatam  the Supreme Personality of Godhead is described in this way:  janmādy asya yato 'nvayād itarataś cārtheṣv abhijñaḥ . The Lord is the origin of all emanations, and He directly and indirectly knows everything about all the activities within His creation. Therefore the Lord is addressed here as  vipaścitam , one who is full of all knowledge or who knows everything. The Lord is the Supreme Soul, and He knows everything about the living entities and their senses.
The word  anidram , meaning “always awake and free from ignorance,” is very important in this verse. As stated in  Bhagavad-gītā  (15.15),  mattaḥ smṛtir jñānam apohanam ca : it is the Lord who gives intelligence to everyone and who causes everyone to forget. There are millions and millions of living entities, and the Lord gives them directions. Therefore He has no time to sleep, and He is never in ignorance of our activities. The Lord is the witness of everything; He sees what we are doing at every moment. The Lord is not covered by a body resulting from  karma . Our bodies are formed as a result of our past deeds ( karmaṇā daiva-netreṇa ), but the Supreme Personality of Godhead does not have a material body, and therefore He has no  avidyā , ignorance. He does not sleep, but is always alert and awake.
The Supreme Lord is described as  tri-yuga  because although He appeared variously in Satya-yuga, Tretā-yuga and Dvāpara-yuga, when He appeared in Kali-yuga He never declared Himself the Supreme Personality of Godhead.
