In our Delhi program. . . There was lecture of a big scientist in Delhi; I forgot his name. He gave very good example that if a man learns how to bark like dog, and if he makes a show, many thousands of people will purchase ticket and go and see how he is barking. (laughter) But by nature's arrangement so many dogs are barking; nobody takes care. You see? So similarly, in the laboratory if a scientist can produce a life some way or other, so they will go and see and give him clap. Just like this aeroplane is flying in the air. Little discrepancy is immediately crash down. So he is getting so much credit, and the scientists also saying, "There is no need of God. Now we have solved all the questions." But nobody is giving credit to Kṛṣṇa, who is floating millions and trillions of stars and planets in the air. So by taking Kṛṣṇa's stock, the petroleum or gas, we become scientist and fly the aeroplane, and Kṛṣṇa has given the petrol, and He has no credit. He has no credit. That is the difference between demons and bhakta. A bhakta sees in everything presence of Kṛṣṇa: "Oh, here is Kṛṣṇa's energy is there. Here is nice taste. Oh, here is Kṛṣṇa." Raso 'ham apsu kaunteya (BG 7.8).
So Kṛṣṇa has manifested Himself in so many ways by His different energies. We have to learn simply to know or see how Kṛṣṇa is working. So here it is stated that rasa-mātrād vikurvāṇād ambhaso daiva-coditāt. Kṛṣṇa is working there. Vikur. . ., transformation does not take place automatically. Just like the other day I gave you the example: there is oil and there is soda, but you can transform into soap by mixing together. That mixing process does not take automatically. There is Kṛṣṇa or Kṛṣṇa's part and parcel, the living entity. We are also Kṛṣṇa's part and parcel. So scientist is working, a devotee sees that Kṛṣṇa is working. That is the difference between nondevotee and devotee. A nondevotee will give credit to the scientist, who is working subordinately under the orders of Kṛṣṇa. That is stated also in the Bhagavad-gītā: sarvasya cāhaṁ hṛdi sanniviṣṭo mattaḥ smṛtir jñānam apohanaṁ ca (BG 15.15). In everyone's heart Kṛṣṇa is there. So one man is working very nicely. He is taking the credit of becoming a scientist. Why the other man cannot do it? Another man is also working in the laboratory.
