While speaking thus, Vidura, whose personal character was esteemed by respectable persons, was insulted by Duryodhana, who was swollen with anger and whose lips were trembling. Duryodhana was in company with Karṇa, his younger brothers and his maternal uncle Śakuni.
It is said that giving good counsel to a foolish person causes the fool to become angry, just as feeding milk to a snake only increases its venomous poison. Saint Vidura was so honorable that his character was looked up to by all respectable persons. But Duryodhana was so foolish that he dared to insult Vidura. This was due to his bad association with Śakuni, his maternal uncle, as well as with his friend Karṇa, who always encouraged Duryodhana in his nefarious acts.
(Srimad Bhagavatam--3:1:14--translation and purport).

Devotee: Verse number two. "What is called renunciation is the same as yoga, or linking oneself with the Supreme, for no one can become a yogi unless he renounces the desire for sense gratification (B.g.6:2)."
Prabhupāda: Here is the point of yoga practice. Yoga means to join. Now in our conditional state, although we are part and parcel of the Supreme, but we are now separated. The same example. This finger is part and parcel of your body, but if it is separated, amputated, it has no value. But so long it is joined with this body, it's value is millions of dollars or more than that. If there is any disease you can spend any amount to cure. Similarly we at the present moment in the conditioned state of material existence, we are separated from God. Therefore we are so much reluctant to speak of God, to understand about God, our relationship with God. We think it is simply waste of time. In this meeting, everyone knows, this temple, Kṛṣṇa consciousness temple, is speaking of God. Or any church. People are not very much interested. They think it is a kind of, what is called, recreation, in the name of spiritual advancement, otherwise it is simply waste of time. Better this time could be used for earning some money. Or enjoying in a club or in a restaurant, sense enjoyment.
So detraction from God means sense enjoyment. Those who are too much addicted to sense enjoyment, they are not, I mean to say, eligible for yoga system. Yoga system is not that, that you go on doing all nonsense in sense gratification and simply sit down meditation. This is simply colossal hoax. It has no meaning. Yoga system first is to sense, controlling the sense, yama, niyama. There are eight different stages of practicing yoga. Yama, niyama, āsana, dhyāna, dhāraṇā, prāṇāyāma, pratyāhāra, samādhi. So in the beginning first of all we shall speak in this chapter, Lord Kṛṣṇa will teach you what is yoga system. Therefore in the beginning Kṛṣṇa says that no one can become a yogi unless he renounces the desire for sense gratification. So anyone who is indulging in sense gratification, he's a nonsense. He's not a yogi. He cannot be a yogi. Yoga system is strictly celibacy, no sex life. That is yoga system. No one can become a yogi if he indulges in sex life. The so-called yogis come to your country and say, "Yes, whatever you like you can do. You meditate, I give you some mantra." These are all nonsense. Here is authoritative statement that no one can become a yogi unless he renounces the desire for sense gratification. This is the first condition.
(Lecture on Bhagavad-Gita--6:2-5--Los Angeles--14th. February, 1969)

So the first beginning is... Here, as it is said by Kṛṣṇa, antavanta ime dehāḥ: don't be attached with this body. The body is material, but even this body is material, it can be spiritualized by the same process, by Kṛṣṇa consciousness. Spiritualized means when this body will forget the materialistic activities. This body, you can utilize for sense gratification. Just generally people are doing. Eating, sleeping, mating and drinking and so on. So you can utilize this body... That is material. But if you engage this body for the service of the Lord, it becomes spiritualized. As I have already explained, the iron rod, constantly in touch with fire, it becomes, at end, it becomes red hot. That is fire. At that time, it acts like fire. You touch that red-hot iron rod anywhere, it will burn. Similarly, this body can be spiritualized, although it is material body. How? Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ (Brs. 1.2.234).
māṁ ca yo vyabhicāreṇa
bhakti-yogena sevate
sa guṇān samatītyaitān
brahma-bhūyāya kalpate
(B.G.14:26)
Brahman. Brahma-bhūyāya kalpate. It at once becomes Brahman. Brahma-bhūyāya kalpate. How? Avyabhicāreṇa bhakti-yogena yaḥ sevate. Therefore this process, arcana... Everyone is engaged only in Kṛṣṇa's service. They are, from the beginning of the day, four o'clock, they are rise from the bed. They offer maṅgala-ārātrika. You are seeing practically. We are demonstrating the Kṛṣṇa con..., how one can become Kṛṣṇa conscious perfectly. Therefore we have brought this Deity. Anyone can do it at home. Where is the difficulty? If these Europeans and Americans, they can do, our Indians which is our heritage, we are born in this land of Bhāratavarṣa, we cannot do it? But we are neglecting. We are so fallen. Mandāḥ sumanda-matayo manda-bhāgyāḥ (S.B.1:1:10). We have become so unfortunate that we cannot take to this process. So whatever we have done, done, that's all right. But now this Kṛṣṇa consciousness movement is there. Everyone should take it very seriously and make his life perfect..
