The senses are meant for glorifying God; those who use them for materialism are like camels eating thorns and tasting their own blood.Listen — Srila Prabhupada Uvaca
] Kṛṣṇa could not go away even an inch from Vṛndāvana [break] on account of the gopīs. What was their education? They were village girls. Not even [break] brāhmaṇa.
Uneducated girls, village girls, but they conquered Kṛṣṇa. So this aural reception is so great. Read little more. Pradyumna: "The human being is endowed with two canine teeth as a concession for such persons who will eat animal food at any cost. It is known to everyone that one man's food is another man's poison. Human beings are expected to accept the remnants of food offered to Lord Śrī Kṛṣṇa, and the Lord accepts foodstuff from the categories of leaves, flowers, fruits, etc.
[Bg. 9.26] "No animal food is offered to the Lord, as prescribed by Vedic scriptures. Therefore, a human being is meant to eat a particular type of food and should not imitate the animals to derive so-called vitamin values. Therefore, a person who has no discrimination in regard to eating is compared with the hogs. The camel is a kind of animal that takes pleasure in eating [break] thorns.
Similarly, a [break] who wants to enjoy family life or the worldly life of [break] enjoyment is compared to the camel. Materialistic life is full of thorns. So one should live only by the prescribed method of Vedic regulations, [break] just to make the best use of a bad bargain. Life in the..." Prabhupāda: Is it not materialistic way of life, he's lying down on thorns?
Is it not like that? [break] So, the so-called materialistic way of life, tātala saikate vāri-bindu-sama suta-mita-ramaṇi-samāje [Śrīla Vidyāpati Ṭhākura], [break] ...society, friendship and love [break] even learn so-called, it is simply full of thorns. That's all. But the camel likes that thorns.
Therefore those who do not understand what is the value of materialistic way of life, they are just like camel. Camel is eating thorn and cutting the tongue, and blood is coming out—it is mixed with thorn—he is thinking that it is very nice food. Actually, he is tasting his own blood, and he is thinking, "Thorn is very nice." Similarly, those who are materialistic person, working day and night very hard, eating his own blood, and he's thinking is very happy life. That's all.
Therefore they are camels. That's all right. Have kīrtana.
