Vedic knowledge is called sruti learning by aural reception. One should actually receive the Vedic message from authorities like Krsna and His representatives. Here Krsna distinguishes everything very nicely, and one should hear from this source. Simply to hear like the hogs is not sufficient; one must be able to understand from the authorities. It is not that one should simply speculate academically. One should submissively hear from Bhagavad-gita that these living entities are always subordinate to the Supreme Personality of Godhead. Anyone who is able to understand this, according to the Supreme Personality of Godhead, Sri Krsna, knows the purpose of the Vedas; no one else knows the purpose of the Vedas.

The word bhajate is very significant. In many places the word bhajate is expressed in relationship with the service of the Supreme Lord. If a person is engaged in full Krsna consciousness in devotional service of the Lord, it is to be understood that he has understood all the Vedic knowledge. In the Vaisnava parampara it is said that if one is engaged in the devotional service of Krsna, then there is no need for a spiritual process to understand the Supreme Absolute Truth. He has already come to the post because he is engaged in the devotional service of the Lord. He has ended all preliminary processes of understanding; similarly, if anyone, after speculating for hundreds of thousands of lives, does not come to the point that Krsna is the Supreme Personality of Godhead and that one has to surrender there, all his speculation for so many years and lives is a useless waste of time.
