Krishna’s explanations of the self, the world, and the source of all existence are the most convincing we’ve ever heard. Don’t just take our word for it, though; you decide:
In the Second Chapter of Bhagavad-gita, the Supreme Lord explained that a living entity is not the material body; he is a spiritual spark. And the Absolute Truth is the spiritual whole. In the Seventh Chapter He spoke of the living entity as being part and parcel of the supreme whole and recommended that he transfer his attention fully to the whole.
Then again in the Eighth Chapter it was said that anyone who thinks of Krishna at the time of quitting his body is at once transferred to the spiritual sky, to the abode of Krishna. And at the end of the Sixth Chapter the Lord clearly said that of all yogis, one who always thinks of Krishna within himself is considered the most perfect. So in practically every chapter the conclusion has been that one should be attached to the personal form of Krishna, for that is the highest spiritual realization.
Nevertheless, there are those who are not attached to the personal form of Krishna. They are so firmly detached that even in the preparation of commentaries to Bhagavad-gita they want to distract other people from Krishna and transfer all devotion to the impersonal brahmajyoti. They prefer to meditate on the impersonal form of the Absolute Truth, which is beyond the reach of the senses and is not manifest.
And so, factually, there are two classes of transcendentalists. Now Arjuna is trying to settle the question of which process is easier and which of the classes is most perfect. In other words, he is clarifying his own position because he is attached to the personal form of Krishna. He is not attached to the impersonal Brahman. He wants to know whether his position is secure.
The impersonal manifestation, either in this material world or in the spiritual world of the Supreme Lord, is a problem for meditation. Actually, one cannot perfectly conceive of the impersonal feature of the Absolute Truth. Therefore Arjuna wants to say, “What is the use of such a waste of time?”
Arjuna experienced in the Eleventh Chapter that to be attached to the personal form of Krishna is best because he could thus understand all other forms at the same time and there was no disturbance to his love for Krishna. This important question asked of Krishna by Arjuna will clarify the distinction between the impersonal and personal conceptions of the Absolute Truth.
