Utilitarians
Scientific knowledge engaged in the service of the Lord and all similar activities are all factually hari-kirtana, or glorification of the Lord.The expert spiritual master knows the art of utilizing everything to glorify the Lord, and therefore under his guidance the whole world can be turned into the spiritual abode by the divine grace of the Lord's servant. One can attain to the highest perfection of life simply by attentive hearing of the transcendental pastimes of the Lord from the right sources, as Sri Narada heard them from the pure devotees (bhakti-vedantas) in his previous life. [SB 1.5.20-26]
