Advise (SB cantos 3 - 4)
Srimad-Bhagavatam
SB Canto 3
SB 3.1.4, Purport:
Actually the whole Bhagavad-gītā is based on the principle of bhakti-yoga. There is a difference between karma and karma-yoga. Karma is regulated action for the enjoyment of the fruit by the performer, but karma-yoga is action performed by the devotee for the satisfaction of the Lord. Karma-yoga is based on bhakti, or pleasing the Lord, whereas karma is based on pleasing the senses of the performer himself. According to Śrīmad-Bhāgavatam, one is advised to approach a bona fide spiritual master when one is actually inclined to question from an elevated level of spiritual understanding. A common man who has no interest in spiritual values has no need to approach a spiritual master just as a matter of following fashion.
