You see the Kṛṣṇa's picture, ānanda-cinmaya-rasa-pratibhāvitābhiḥ (Bs. 5.37). He's enjoying in blissfulness. This Rādhā and Kṛṣṇa, this is enjoyment, but this enjoyment is not like here, the young boys and girls, they enjoy. It is not like that. Because here the ānanda is temporary, it is not eternal, but that ānanda, rādhā-kṛṣṇa-praṇaya-vikṛtiḥ, is eternally blissful. So Kṛṣṇa is canvassing everyone that, "You come to Me. Here also you will have this eternal ānanda, eternal blissfulness." You are after loving affairs, but here in this material world, actually there is no love. It is only lust. And even if we accept that this is love, it will not exist. It will be finished.
Therefore in Vedic literature we find that ramante yoginaḥ anante (CC Madhya 9.29): "Those who are yogīs, those who are transcendentalist . . ." They also . . . every one of us are seeking after pleasure, ānanda, but the yogīs, either these jñāna-yogī, dhyāna-yogī or karma-yogī or bhakta-yogī . . . there are different kinds of yogīs, but the yogī means the person who wants to connect himself with the eternal happiness. That is called yogī: one who is not satisfied with this temporary, material happiness.
Just like Śaṅkarācārya, he also says that, brahma satyaṁ jagan mithyā: "You are trying to derive pleasure from this material world, but it is false." He also says. If you want real pleasure, then brahma-saukhyam—you have to seek pleasure in the Brahman. Similarly, we find in Śrīmad-Bhāgavatam, in the instruction of Ṛṣabhadeva, He says . . . he's instructing His sons, tapo divyaṁ putrakā yena śuddhyet sattvaṁ yasmād brahma-saukhyaṁ tv anantam (SB 5.5.1). He's advising His sons. "His sons" means everyone, He's advising. What is that?
- na ayaṁ dehaḥ deha-bhājāṁ nṛloke
- kaṣṭān kāmān arhati yad viḍ-bhujām ye
- (SB 5.5.1)
"My dear sons, this human form of body is not meant for continuously hard labor simply for sex enjoyment." Simply for sex enjoyment. Because in this material world, the enjoyment, the highest enjoyment one can perceive, that is sex. Therefore in the material world those who are materialists, they are trying to exact happiness simply by that sex life.
