Sarvam etad ṛtaṁ manye (BG 10.14). "I take it, I believe it that whatever You have spoken, they are all right. And Your Personality, Your Personality of Godhead, is very difficult to understand. And therefore You cannot be known by even the demigods. You cannot be known even by the demigods." That means the Supreme Personality Godhead cannot be known even by greater personalities than the human being, and how a human being can understand Śrī Kṛṣṇa without becoming His devotee?
Therefore Bhagavad-gītā should be taken up in a spirit of devotee of Lord Śrī Kṛṣṇa. One should not think that he is equal, on the same level of Śrī Kṛṣṇa, or one should not think that He is an ordinary personality, maybe a very great personality. No. Lord Śrī Kṛṣṇa is the Supreme Personality of Godhead. So at least theoretically, on the statement of Bhagavad-gītā or on the statement, assertion of Arjuna, the person who is trying to understand the Bhagavad-gītā, we should accept Śrī Kṛṣṇa as the Supreme Personality of Godhead, and then, with that submissive spirit... Unless one receives this Bhagavad-gītā in a submissive spirit and aural reception, it is very difficult to understand Bhagavad-gītā because it is a great mystery.
So in this Bhagavad-gītā... We may survey what is this Bhagavad-gītā. This Bhagavad-gītā is meant for delivering persons, persons from the nescience of this material existence. Every man is in difficulty in so many ways, as Arjuna also was in difficulty in the matter of fighting the battle of Kurukṣetra. And as such he surrendered unto Śrī Kṛṣṇa, and therefore this Bhagavad-gītā was spoken. Similarly, not only Arjuna but every one of us is always full of anxieties due to our, this material existence. Asad-grahāt. It is... Our existence is in the environment, or atmosphere, of nonexistence. But actually, we are not nonexistent. Our existence is eternal, but some way or other we are put into this asat. Asat means which does not exist.
Now out of so many human being who are actually inquiring about his position as to what he is, why he is put into this awkward position of suffering... Unless one is awakened to this position, that "Why I am suffering? I do not want all these sufferings. I have tried to make a solution of all these sufferings, but I have failed," unless one is in that position, he is not to be considered a perfect human being. Humanity begins when this sort of inquiries are awakened in one's mind. In the Brahma-sūtra this inquiry is called brahma-jijñāsā. Athāto brahma jijñāsā. And every activity of the human being is to be considered a failure without having this inquiry in his mind. So persons who have awakened this inquiry into his mind as to "What I am, why I am suffering, wherefrom I have come or where I shall go after death," when these inquiries come, are awakened in the mind of a sane human being, then he is practically the right student for understanding Bhagavad-gītā. And he must be śraddhāvān. Śraddhāvān. He must have respect, a fond respect in the Supreme Personality of Godhead. Such a person, as the ideal person was Arjuna.
