Translation: 
The Lord’s potencies are innumerable. As He lies down in the water of devastation, I am born as the total universal energy from the navel lake in which the lotus sprouts. I am now engaged in manifesting His diverse energies in the form of the cosmic manifestation. I therefore pray that in the course of my material activities I may not be deviated from the vibration of the Vedic hymns.
Purport: 

Every person engaged in the transcendental loving service of the Lord in this material world is prone to so many material activities, and if one is not strong enough to protect himself against the onslaught of material affection, he may be diverted from the spiritual energy. In the material creation Brahmā has to create all kinds of living entities with bodies suitable to their material conditions. Brahmā wants to be protected by the Lord because he has to contact many, many vicious living entities. An ordinary brāhmaṇa may fall from the brahma-tejas, or the power of brahminical excellence, due to his association with many fallen, conditioned souls. Brahmā, as the supermost brāhmaṇa, is afraid of such a falldown, and therefore he prays to the Lord for protection. This is a warning for one and all in the spiritual advancement of life. Unless one is sufficiently protected by the Lord, he may fall down from his spiritual position; therefore one has to pray constantly to the Lord for protection and the blessing to carry out one’s duty. Lord Caitanya also entrusted His missionary work to His devotees and assured them of His protection against the onslaught of material affection. The path of spiritual life is stated in the Vedas to be like the edge of a sharpened razor. A little inattentiveness may at once create havoc and bloodshed, but one who is a completely surrendered soul, always seeking protection from the Lord in the discharge of his entrusted duties, has no fear of falling into material contamination.
