Question: What is the function of yoga-māyā?
Answer: Just as jīva-māyā obscures awareness of the supremacy of Bhagavān in the material world, yoga-māyā suppresses awareness of the supremacy of Bhagavān in the spiritual world.
Question: Then Bhagavān and His devotees are also in a type of avidyā?
Answer: Yes, it can be called avidyā, but it is of a different type than the avidyā here. In the spiritual world, Bhagavān lacks the awareness that He is Bhagavān. If He and His devotees did not forget the fact that He is Bhagavān, then He would not be able to give pleasure to His devotees as they would be in awe of Him. Therefore, His forgetfulness is also for the enjoyment of His devotees and is under His control, and by His wish. Both jīva-māyā and yoga-māyā are His potencies, and serve Him alone. This is the difference between us and Him.
Question: So Bhagavān in the Dāmodara-līlā truly does not know He is Bhagavān?
Answer: Yes. He is afraid of His mother. He has no awareness that He is Bhagavān. At the same time, He does not stop being Bhagavān. His mother tried to bind Him, but couldn’t. Till He consented.
