SB 3.9.29
sri-bhagavan uvaca
ma veda-garbha gas tandrim
sarga udyamam avaha
tan mayapaditam hy agre
yan mam prarthayate bhavan
Translationby His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Supreme Personality of Godhead then said: O Brahma, O depth of Vedic wisdom, be neither depressed nor anxious about the execution of creation. What you are begging from Me has already been granted before.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Any person authorized by either the Lord or by His bona fide representative is already blessed, as is the work entrusted to him. Of course, the person entrusted with such a responsibility should always be aware of his incapability and must always look for the mercy of the Lord for the successful execution of his duty. One should not be puffed up because he is entrusted with certain executive work. Fortunate is he who is so entrusted, and if he is always fixed in the sense of being subordinate to the will of the Supreme, he is sure to come out successful in the discharge of his work. Arjuna was entrusted with the work of fighting on the Battlefield of Kuruksetra, and before he was so entrusted, the Lord had already arranged for his victory. But Arjuna was always conscious of his position as subordinate to the Lord, and thus he accepted Him as the supreme guide in his responsibility. Anyone who takes pride in doing responsible work but does not give credit to the Supreme Lord is certainly falsely proud and cannot execute anything nicely. Brahma and persons in the line of his disciplic succession who follow in his footsteps are always successful in the discharge of loving transcendental service to the Supreme Lord.
