Our this Kṛṣṇa consciousness movement is educating that the varieties of service should be concentrated for the satisfaction of Kṛṣṇa. That is pravṛtti. And what is not satisfying Kṛṣṇa, against the will of Kṛṣṇa, that should be avoided. That is called nivṛtti. Anukūlyasya saṅkalpaḥ pratikūlyasya varjanam (Hari-bhakti-vilāsa 11.676). This is called surrender. Surrender means that Kṛṣṇa asking surrender: sarva-dharmān parityayja mām ekaṁ śaraṇaṁ vraja. What is the surrender means? Surrender means that "Kṛṣṇa, I am surrendering unto You. I was acting whimsically, by the dictation of my different senses," kāma, krodha, lobha, moha, mātsarya, like that. Na kāmādīnāṁ katidha na katidhā pālitā durnideśa. The śāstra says you should not steal—an example. But I am stealing. Why? Na kāmādīnāṁ katidha na katidhā pālitā durnideśa (CC Madhya 22.16). I know I should not steal; therefore I go to somebody's house very secretly, or push my hand very secretly in one's pocket. I know that I should not do this, but I am forced to do it. Why? Dictated by my lusty desire. So I have become servant of my six senses. Manaḥ saṣṭhanīndriyāni prakṛti-sthāni karṣati (BG 15.7). This is our position. Kamāninā kulya . . . everyone knows. A thief knows that if he commits theft he'll be punished, either by the police or by the laws of God. Everyone knows, but he still commits theft. Why? This is dictated by the lusty desires.
So pravṛtti means we are dictated by our kāma, krodha, lobha, moha, mātsarya, and we should agree to be dictated by Kṛṣṇa, that's all. That is intelligent. Pravṛtti, nivṛtti. Our pravṛtti is to abide by the dictation of the senses, and when we learn not to abide by the dictation of the senses but to abide by the orders of Kṛṣṇa or His representative, then your life are successful. This teaching, this learning, means Kṛṣṇa consciousness. It is not difficult. Everyone can do it. Simply he has to change: instead of being dictated by the senses, one should be dictated by Kṛṣṇa. That requires qualification. Kṛṣṇa is there, everyone's heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). Kṛṣṇa is not far away. But you have to search out where is Kṛṣṇa within your heart. That is called yoga.
