Srimad Bhagavatam Canto 09, Chapter 18, Text 25

SB 9.18.25

durmana bhagavan kavyah
 paurohityam vigarhayan
stuvan vrttim ca kapotim
 duhitra sa yayau purat
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
As Sukracarya listened to what had happened to Devayani, his mind was very much aggrieved. Condemning the profession of priesthood and praising the profession of uñcha-vrtti [collecting grains from the fields], he left home with his daughter.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
When a brahmana adopts the profession of a kapota, or pigeon, he lives by collecting grains from the field. This is called uñcha-vrtti. A brahmana who takes to this uñcha-vrtti profession is called first class because he depends completely on the mercy of the Supreme Personality of Godhead and does not beg from anyone. Although the profession of begging is allowed for a brahmana or sannyasi, one does better if he can avoid such a profession and completely depend on the mercy of the Supreme Personality of Godhead for maintenance. Sukracarya was certainly very sorry that because of his daughter’s complaint he had to go to his disciple to beg some mercy, which he was obliged to do because he had accepted the profession of priesthood. In his heart, Sukracarya did not like his profession, but since he had accepted it, he was obliged to go unwillingly to his disciple to settle the grievance submitted by his daughter.
