Slacken the knot of material desire and return to your eternal nature as servant of Krishna.Listen — Srila Prabhupada Uvaca
Pradyumna: Translation: "When the strong knot in the heart of a person implicated in material life due to the results of past action is slackened, one turns away from his attachment to home, wife and children. In this way, one gives up the basic principle of illusion [I and mine] and becomes liberated. Thus one goes to the transcendental world." Prabhupāda: yadā mano-hṛdaya-granthir asya karmānubaddho dṛḍha āślatheta tadā janaḥ samparivartate 'smād muktaḥ paraṁ yāty atihāya hetum [SB 5.5.9] So the conclusion is given here: one should be completely satiated from this attachment of sex, then he is liberated. Liberation means no more material life, and the basic principle of material life is sex.
Therefore whole Vedic civilization is based on to train people how he becomes free from sex desire. The great emperor Yāmunācārya, he gave his experience how he became liberated from sex desire: yad-avadhi mama cetaḥ kṛṣṇa-padāravinde nava-nava-dhāmany rantum āsīt tad-avadhi bata nārī-saṅgame smaryamāne bhavati mukha-vikāraḥ suṣṭhu niṣṭhīvanaṁ ca Since... He gives his experience, "Since I have given my mind and heart in the service of yad-avadhi mama cetaḥ kṛṣṇa-padāravinde, at the lotus feet of Lord Kṛṣṇa, and I have increased my transcendental, blissful life by rendering such loving service, since then, even if I think of sex life," yad-avadhi mama cetaḥ, tad-avadhi bata nārī-saṅgame smaryamāne, "even sex life, thinking of it, it becomes so abominable that I spit on it." So this is the test of advancement of Kṛṣṇa conscious life. Śrī Caitanya Mahāprabhu, when He delivered Jagāi-Mādhāi... This Jagāi-Mādhāi was debauch—drinking, illicit sex, meat eating and these things, degradation.
These four principles are the four pillars of degradation. Therefore we prohibit, that if you want to make progress in Kṛṣṇa consciousness, you must give up these four principles. So Caitanya Mahāprabhu made this condition, that "If you promise that you will give up these four principles of sinful life, then I will accept you, never mind whatever you have done in the past." Every man is sinful, there is no doubt about it, more or less. That is not disqualification.
If he agrees to give up that, then immediately he becomes liberated. That is Kṛṣṇa also says in the Bhagavad..., ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi. Liberation is not very difficult. It can be atained in one minute, provided you want to take it.
Just like Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi [Bg 18.66] So if you are free from the resultant action of sinful life, then you are liberated. If you get shelter at the lotus feet of Kṛṣṇa and do not act in such a way that you again fall down, then you are liberated. Liberation means, we have several times discussed, hitvā anyathā-rūpaṁ svarūpeṇa vyavasthitiḥ [SB 2.10.6]. Our svarūpa, means original, constitutional position, is jīvera svarūpa haya nitya-kṛṣṇa-dāsa [Cc Madhya 20.108-109], eternally servant of Kṛṣṇa.
So as soon as we place ourselves in our original place, then you are liberated immediately. If we determine, decide finally, that we shall now continuously, vehemently fixed up in Kṛṣṇa consciousness, very simple thing... Kṛṣṇa consciousness is described by Kṛṣṇa in the Bhagavad-gītā: man-manā bhava mad-bhaktaḥ. That's all. "Always think of Me," man-manāḥ, and bhava mad-bhaktaḥ, "be ready always to serve Me." Bhakta means, where there is bhakti and Bhagavān.
Then bhakta. If there is no Bhagavān, and there is no activities to serve Bhagavān, there is no bhakta also. They are demons. So bhakta means there must be Bhagavān.
