You are eternally a servant; serve Krishna instead of serving your senses, and find real happiness.Listen — Srila Prabhupada Uvaca
Śrīmad-Bhāgavatam 6.1.1 — May 21, 1975, Melbourne 750521SB-MELBOURNE [66:13 Minutes] SB-06.01.01_750521SB-MELBOURNE Prabhupāda: ...sudevāya. Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. [devotees chant responsively] rajovaca pravṛtti-mārgaḥ kathita ādau bhagavatā yathā krama-yogopālabdhena brahmaṇā padasaṁsṛtiḥ [SB 6.1.1] Hmm.
So we have discussed the last two days what is the aim of life. So this whole Kṛṣṇa consciousness movement is diverting the aim of life. There are two ways. Our present position, the aim of life is sense gratification.
Yan maithunādi-gṛhamedhi-sukhaṁ hi tuccham [SB 7.9.45]. Material life means sense gratification, as much as possible. And the central point of sense gratification is sex life. Yan maithunādi.
Maithuna means sexual intercourse. This is the machine to keep the living entity bound up under the condition of material nature. We are conditioned by the material nature. We are thinking we are free.
We are not free. That is not the fact. Therefore Kṛṣṇa says in the Bhagavad-gītā that "You are thinking that you are free, whatever you like you can do, enjoy sense gratification—but under condition. You are not free." So there are different grades of sense gratification, but the point is sense gratification.
The cats and dogs, the animals, they are also satisfying their senses, and the human being also engaged in the same business. The cats and dogs, they are eating to their taste; the human being is also eating to their taste. The standard may be different, but the taste is the same. Either you have sex intercourse with beautiful wife or husband or as sex intercourse between the she-dog and he-dog, the enjoyment is the same.
Just like if you have got a palatable food, either you put it into a golden pot or if you put it into iron pot, the taste is the same. The taste is not different. One may think that "I am eating in golden pot; therefore I am advanced." But a learned man will say that "Whether you have changed the taste?" Either you drink something palatable in a golden pot or in iron pot or paper pot, the taste is the same. So this is called pravṛtti-mārga.
