Simply by chanting, you'll be purified. Ceto-darpaṇa-mārjanam (CC Antya 20.12). Go on chanting Hare Kṛṣṇa. And the beginning will be ceto-darpaṇa-mārjanam, because we have got our heart . . . everyone—we are living entity—we have got heart that is full with dirty things. That dirty things is "I am this," "I am that," "I am that," "I am that," that dirty things. So we have to cleanse these dirty things, that "I am European," "I am American," "I am Hindu," "I am Muslim," "I am this," "I am that." These are all dirty things. You have to simply think, "I am eternal servant of Kṛṣṇa." Jīvera 'svarūpa' haya-nitya kṛṣṇa dāsa (CC Madhya 20.108-109). When you think like that, that "I am eternal servant of Kṛṣṇa," then all these dirty things will automatically vanish.
That is brahma-bhūtaḥ stage. Brahma-bhūtaḥ prasannātmā (BG 18.54). As soon as you become realized soul, that "My position is that I am eternal servant of Kṛṣṇa . . ." I am nobody's servant. But if one becomes Kṛṣṇa's servant, he becomes everyone's servant. That is the Kṛṣṇa consciousness. Why you are trying to preach Kṛṣṇa consciousness all over the world? Because we have accepted this principle that, "I am Kṛṣṇa's servant. Kṛṣṇa wants to deliver these rascals from this misconception of life, so let me do something for Kṛṣṇa." This is Kṛṣṇa consciousness. And if you are servant of Kṛṣṇa, if you actually realize, then you have to do something on behalf of Kṛṣṇa, what Kṛṣṇa wants. The first-class servant is he when he serves the master without asking for it. If he understands that, "Master is now in need of this thing," if he brings it, oh, first-class servant. He's first-class servant, because he knows the master wants it.
So Kṛṣṇa wanted, as Kṛṣṇa that, "All these rascals may give up their so foolish engagements and surrender unto Me." Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ (BG 18.66). That was Kṛṣṇa's last word in the Bhagavad-gītā. Kṛṣṇa wants this, that "These rascals they are suffering in this material condition of life, three miserable condition, and still, they are so rascal, they do not come to their senses. Still, they want to remain servant of māyā. So let Me directly say: 'You rascal, give up all this engagement. Surrender unto Me.' " That is Kṛṣṇa. But they will not do it. "Why shall I surrender to You? I have got so many things. I have got my nation, I have got my family, I have got my this, I have got . . . why shall I surrender to You, give up everything?" Such a rascal. Cannot be convinced any way. Whole world is servant of somebody, but he declines to become servant of Kṛṣṇa. This is the disease, material disease. He will remain servant of thousands and millions of establishment and person, but he will disagree. As soon as Kṛṣṇa says that, "You give up. You become My servant," "No, no. Why can I? Why shall I do it?" This is materialist.
