PURPORT

The heavenly demigods are certainly more intelligent, powerful and beautiful, and yet they had to take help from Arjuna because of his Gandiva bow, which was empowered by the grace of Lord Sri Krsna. The Lord is all-powerful, and by His grace His pure devotee also can be as powerful as He may desire, and there is no limit to it. And when the Lord withdraws His power from anyone, he is powerless by the will of the Lord.
