Madhusūdana. Kṛṣṇa is described here as Madhusūdana, the killer of the demon Madhu. Madhu-kaiṭabha-ari. So Arjuna was attacked by a demon of forgetting his duty, being too much afflicted by bodily relationship. This is our position. In this material world, we are so much attached to this bodily relationship that it is to be considered just like we are ghostly haunted. In a poetry, Prema-vivarta, it is said that piśācī pāile yena mati-cchanna haya, māyā-grasta jīvera haya se bhāva udaya. Māyā-grasta jīva. Māyā-grasta. Māyā means illusion, hallucination. So we are, in this material world, we are all illusioned. Illusioned means accepting something as fact which is not. Something... Just like in dream we see sometimes I am attacked with a tiger; my head is being cut off. So many things. So actually there is no tiger, my head is not being cut off, but still, I am crying: "Oh, here is a tiger, here is a tiger!" So our attachment for this world is like that. It is illusion. I am thinking that "Without me, everything will be spoiled. My presence is required." And so on, so on. Just like sometimes our political leaders. Each and every one of them thinks that without him, the whole situation will be spoiled. Even Mahatma Gandhi, he was so attached that he would not retire from political life—unless he was killed. The attachment was so strong. But after passing away of Mahatma Gandhi or Jawaharlal Nehru or so many big, big leaders, the world is going on. There is a Bengali proverb that "When the king dies, it does not mean the kingdom stops." The kingdom goes on. But when, so long, the leader or the person in charge remains there, he thinks that "Without me, everything will be spoiled." This is called māyā. This is called illusion.
According to Vedic system, therefore, there is forced renunciation. Nobody wants to retire from family life, but the Vedic injunction is that after one has passed fifty years, he must leave his family life. Pañcāśordhvaṁ vanaṁ vrajet. In the beginning, as a student life, he's trained up, brahmacārī, undergoing severe austerities, penances, and taking instruction from the spiritual master about the temporary existence of this material world. In this way, he's trained up very nicely. And even after training, if he appears to be attached to this material world, he's allowed to go home and marry. And some of the brahmacārīs are allowed to remain naiṣṭhika-brahmacārī, without going home and accepting a wife. But one who cannot, he's allowed to accept wife and become a householder and remain there for twenty-five years. Because generally, the brahmacārī was going home at the age of twenty-four years, twenty-five years. So after marriage, he may get a child. So living there for twenty-five years, means the child is grown up. Then the husband and wife takes leave, not leaving for good, but vānaprastha, traveling in pilgrimages like Vṛndāvana, Prayāga. That was the system. And after two months, again he comes back and remains home for another two months. Again goes out. In this way, the whole process is how to give up attachment from this family life, from this world. And when he's trained up fully, he takes sannyāsa. That is our Vedic system.
