The bhakti-yoga means acting by pleasing the Lord. That's all. That is the verdict of Śrīmad-Bhāgavatam. You are not forbidden to do this thing or that thing, but you have to see only whether by your action the Supreme Lord is satisfied. That's all. That much knowledge you must have. Then your life will be successful. The Śrīmad-Bhāgavata says:
- ataḥ pumbhir dvija-śreṣṭhā
- varṇāśrama-vibhāgaśaḥ
- svanuṣṭhitasya dharmasya
- saṁsiddhir hari-toṣaṇam
- (SB 1.2.13)
Ataḥ pumbhir dvija-śreṣṭhā. This verse was spoken by Sūta Gosvāmī, who was speaking before a very learned gathering at Naimiṣāraṇya. It is the system of Vedic system, that . . . not Vedic system; everywhere, all over the world. Any civilized society there is nice speaker, learned speaker, and many persons hear him.
That is the system from very old time. So Sūta Gosvāmī, he was representative of Śukadeva Gosvāmī, the speaker of Śrīmad-Bhāgavatam, and he was addressing very learned brahmins.
So he's addressing, dvija-śreṣṭhā. Śreṣṭhā means the, I mean to say, picked-up, the topmost of the brahmins. They were topmost of the brahmins; still, they require knowledge. Knowledge is so nice that even if you think that you are very learned, you are well versed in everything, still, you require knowledge. That should be our motto.
Don't think that, "I have finished." Caitanya Mahāprabhu has taught this lesson in His life, that He represented Himself as a fool. So everyone should think of himself that, "I am still a fool."
