Srimad Bhagavatam Canto 05, Chapter 04, Text 17

SB 5.4.17

dravya-desa-kala-vayah-sraddhartvig-vividhoddesopacitaih sarvair api kratubhir yathopadesam sata-krtva iyaja.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Lord Rsabhadeva performed all kinds of sacrifices one hundred times according to the instructions of the Vedic literatures. Thus He satisfied Lord Visnu in every respect. All the rituals were enriched by first-class ingredients. They were executed in holy places according to the proper time by priests who were all young and faithful. In this way Lord Visnu was worshiped, and the prasada was offered to all the demigods. Thus the functions and festivals were all successful.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
It is said, kaumara acaret prajño dharman bhagavatan iha (Bhag. 7.6.1). A ritual should be performed by young men, even boys, at a tender age in order for the ritual to be performed successfully. From childhood, people should be trained in Vedic culture, especially in devotional service. In this way, one can perfect one’s life. A Vaisnava does not disrespect the demigods, but on the other hand he is not so foolish that he accepts each and every demigod as the Supreme Lord. The Supreme Lord is master of all demigods; therefore the demigods are His servants. The Vaisnava accepts them as servants of the Supreme Lord, and he worships them directly. In the Brahma-samhita, the important demigods — Lord Siva, Lord Brahma and even the incarnations and expansions of Lord Krsna like Maha-Visnu, Garbhodakasayi Visnu and all the other visnu-tattvas, as well as the sakti-tattvas like Durgadevi — are all worshiped by the process of worshiping Govinda with the words govindam adi-purusam tam aham bhajami. A Vaisnava worships the demigods in relation to Govinda, not independently. Vaisnavas are not so foolish that they consider the demigods independent of the Supreme Personality of Godhead. This is confirmed in Caitanya-caritamrta. Ekale isvara krsna, ara saba bhrtya: the supreme master is Krsna, and all others are His servants.
