Similarly, there is another force superior to the air, and another and another, until ultimately we arrive at Krṣṇa. This is real research. Krṣṇa controls nature just as an engineer controls a train. The engineer controls the locomotive, which pulls one car, and that car in turn pulls another, which pulls another, and so the whole train is moving. Similarly, with the creation, Krṣṇa gives the first push, and then, by means of successive pushes, the entire cosmic manifestation comes into being and is maintained. This is explained in  Bhagavad-gītā  (9.10).  Mayādhyakṣena prakṛtiḥ sūyate sacarācaram:  "This material nature is working under My direction and is producing all moving and unmoving beings." And in the Fourteenth Chapter [Bg. 14.4] Krṣṇa says:
sarva-yoniṣu kaunteya mūrtayaḥ sambhavanti yāḥ tāsāṁ brahma mahad yonir ahaṁ bīja-pradaḥ pitā
"All species of life are made possible by birth in this material nature, O son of Kuntī, and I am the seed-giving father." For example, if we sow a banyan seed, a huge tree eventually comes up and, along with it, millions of new seeds. Each of these seeds can in turn produce another tree with millions of new seeds, and so on. This is how Kṛṣṇa, the original seed-giving father, is the primary cause of everything we see.
Unfortunately, the scientists observe only the immediate cause; they cannot perceive the remote cause. Krşna is described in the  Vedas  as  sarva-kāraṇa-kāraṇam  [ Bs.  5.1], the cause of all causes. If one understands the cause of all causes, then he understands everything.  Yasmin vijñāte sarvam evam vijñātam bhavati:  "If one knows the original cause, the subordinate causes are automatically known." Although the scientists are searching after the original cause, when the  Vedas , perfect knowledge, declare the original cause to be the Supreme Personality of Godhead, the scientists won't accept it. They keep to their partial, imperfect knowledge. This is their disease.
The Cosmic Machine
Śrīla Prabhupāda.  Scientists do not know that there are two types of energy-inferior and superior-although they are actually working with these two energies every day. Material energy can never work independently; it must first come in contact with spiritual energy. So how can people accept that the entire cosmic manifestation, which is nothing but matter, has come about automatically? A competent machine does not work unless a man who knows how to work it pushes a button. A Cadillac is a nice car, but if it has no driver, what is the use of it? So the material universe is also a machine.
People are amazed at seeing a big machine with many, many parts, but an intelligent person knows that however wonderful a machine may be, it does not work unless an operator comes and pushes the proper button. Therefore, who is more important-the operator or the machine? So we are concerned not with the material machine-this cosmic manifestation-but with its operator, Kṛṣṇa. Now you may say, "Well, how do I  know  that He is the operator?" Kṛṣṇa says,  mayādhyakṣeṇa prakṛtiḥ sūyate sacarācaram: [Bg. 9.10]  "Under My direction the whole cosmic manifestation is working." If you say, "No, Kṛṣṇa is not the operator behind the cosmos," then you have to accept another operator, and you must  present  him. But this you cannot do. Therefore, in the absence of your proof, you should accept mine.
