"We are manufacturing so many ways of happy life, this 'ism,' that 'ism,' that plan, that plan. So many plans. We are seeing suggestion, so many suggestions, in the television: 'This is the problem. This is the suggestion. This is problem.' Full of new, new problem, new, new suggestion. But because we are lacking this rāja-vidyā, the king of knowledge, we are perplexed. But if you know that Kṛṣṇa is the root cause of everything, and if we serve Kṛṣṇa, then every problem will be solved immediately. This is called rāja-vidyā. Rāja-vidyā rāja-guhyam. And pratyakṣāvagamaṁ dharmyam. Just like I have given the example that the different parts of the body, they are suffering from different diseases. But if you make good treatment, if you take the proper medicine and put it in the stomach, then immediately you will understand, 'Yes, I am getting relief.'
Or suppose you are hungry. You are... On account of your hunger you are feeling headache. You cannot see through your eyes properly, you cannot hear, you cannot work—so many things, problems, will arise. But as soon as you put some foodstuff, nourishing foodstuff, immediately you'll feel strength and you'll (be) happy, happy. That is called pratyakṣa. Pratyakṣa means 'directly.' Avagamaṁ dharmyam. If you are hungry and if you are given very nice, nutritious, palatable food, you haven't got to take any certificate from others. You'll understand yourself, 'Yes, I am now feeling strength. I am now feeling energy.' This is called pratyakṣāvagamaṁ dharmyam. Similarly, if you take to Kṛṣṇa consciousness—that is the process—then you'll feel automatically how you are satisfied. Pratyakṣāvagamaṁ dharmyam.
These boys, these American, European—they are all Western country, belong to the Western country— why they are sticking to this Kṛṣṇa consciousness? Because they are feeling directly happiness. There is no doubt about it. Ask any one of them. This is pratyakṣāvagamaṁ dharmyam. And susukham. To execute this dharma, this transaction, it is very, very happy. Don't you see? What is their business? They are not going to the factories to work twelve hours. They are simply chanting and dancing. This is their business. And when they are hungry, they are taking very nutritious prasādam. This is called susukham. Very happy. They haven't got to work in the factory, in the mine, in the sea for extracting oil or coal. They haven't got. We have no such business. We are simply engaged in chanting, dancing and eating Kṛṣṇa prasādam. Susukham. Pratyakṣāvagamam. Practically you can perceive. And how happy it is, you can perceive. Kartum avyayam. To execute this business of Kṛṣṇa consciousness is so easy and happy, and whatever you do, a little, it is your permanent asset. It will never be spoiled."
