You cannot understand by your erudite scholarship what is Kṛṣṇa. It is not possible. Then Kṛṣṇa would have instructed Bhagavad-gītā to..., finding out a very great Vedantist. No. Kṛṣṇa found Arjuna. What was Arjuna? Arjuna was a gṛhastha. Arjuna was a kṣatriya, and although a soldier... A soldier is not expected to become a Vedantist. We recruit soldiers not from the Vedantists' group. One who can fight, one who has got strength—we recruit soldier. So Arjuna was not very qualified in that way to understand Bhagavad-gītā or instruction, but Kṛṣṇa said, "Yes, I will speak, speak to you. This Bhagavad-gītā, the paramparā is lost, so I shall again speak the old thing to you." "Why to me?" Bhakto 'si priyo 'si me: (BG 4.3) "Because you are My bhakta. You are My priya." So by scholarship one cannot understand Bhagavad-gītā. That is not possible. One must become a servant of the servant of Kṛṣṇa (CC Madhya 13.80). Then one can understand what is Bhagavad-gītā. Otherwise it (is) not possible.
So evaṁ janaṁ nipatitaṁ prabhavāhi-kūpe. Ahi kūpa. Ahi means the serpent. So we have got these serpents surrounded by us, surrounded, all round. What are the serpents? The senses. Everyone, we are in the dark well surrounded by serpents, this body. Bhaktivinoda Ṭhākura has sung this song, śarīra avidyā-jāl, jaḍendriya tāhe kāla. Kāla means serpents, kāla-sarpa. Kāla-sarpa, it can bite at any moment and finish you. We are being bitten every moment. It is Kṛṣṇa's grace that we are living. Otherwise our senses are so dangerous that it can bring me down at any moment, kāla-sarpa. There are many places, kāla-sarpa-paṭalī protkhāta-daṁstrāyate. One devotee says, "Yes, I am surrounded by kāla-sarpa, the serpent, that's nice, but I can break the teeth." But if kāla-sarpa is the... What is called, that? Fangs? If they are broken—they are taken out—they are no more dangerous. Dangerous. They are dangerous so long the fangs are there. So protkhāta-daṁstrāyate. Śrī Prabodānanda Sarasvatī said, kāla-sarpa-paṭalī protkhāta-daṁstrāyate: "Yes, I have got my kāla-sarpas, but by the grace of Caitanya Mahāprabhu, I have broken the fangs, so it is no more fearful." How it is possible? By the mercy of Caitanya Mahāprabhu it is possible. Just like you can break the fangs of the... There are expert snake charmer. Because this poison is required for some medicinal purpose, so they take it out. Then it is useless. But they again grow. The body is so made of the snake, even if you take once the fangs, again it grows. That is stated here, that how it is possible? Kāmābhikāmam anu yaḥ prapatan prasaṅgāt. Once it may be broken, but if you have bad association, then again it will grow. Kāmābhikāmam. One kāma, one lusty desire, produces another lusty desire. In this way, one after another, this is going on. That is the cause of our repeated birth and death. Bhūtva bhūtvā pralīyate (BG 8.19). So therefore, if we want to enter into bhakti platform, then we should give up this. Anyābhilāṣitā-śūnyam. Anyābhilāṣitā-śūnyam (Brs. 1.1.11).
