PURPORT

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