Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Being always devoted to the demigods, the spiritual master and the Supreme Lord, Visnu; endeavoring for advancement in religious principles, economic development and sense gratification [dharma, artha and kama]; believing in the words of the spiritual master and scripture; and always endeavoring with expertise in earning money — these are the symptoms of the vaisya.
