You may have tractor, you may have very good arrangement for producing food, machinery; but still, if the land or earth does not produce food, your this tractor or all other arrangements will be failure. So after all, we should know the supply of things are in the hands of the material nature. And material nature works under the direction of God. That is stated in Bhagavad-gītā: mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10). Prakṛti means this material nature.
You don't think material nature is blind. Material nature has got her intelligence, and she is taking intelligence from the Supreme Lord. And according to that, she is supplying food or grains and everything. Because you get everything from the earth. Either you take metal or this wood or water or food grains, whatever you are taking, using, you are exploiting the resources of material nature, but material nature is the agent of God. Material nature is an energy of God. So if God does not wish to supply you, however you may bring tractor and anything . . . just like in desert. In desert you cannot make it fertile because there that particular tract of land is forbidden by God: "No, nothing should be produced." You cannot do it. If you have got producing power, then why don't you produce sufficient grains and vegetables in the desert? That is not possible.
So after all, we have to accept the supreme authority, the Personality of Godhead. Even if you study scrutinizingly, very scientifically or, whatever you may say, philosophically, you will have to accept a supreme arrangement, a supreme hand over everything. That is called Kṛṣṇa consciousness. Kṛṣṇa consciousness means a person who is Kṛṣṇa conscious, he can see everything. He can see in everything the hand of God. That is Kṛṣṇa consciousness. If you see . . . a Kṛṣṇa conscious person sees a flower. He sees the flower—created . . . creation of God, Kṛṣṇa. "Oh, Kṛṣṇa is so artistic that He has created this flower by His energy so nicely, so decorately, so good flavor. So it is Kṛṣṇa's thing. Let me offer it to Kṛṣṇa." This is Kṛṣṇa consciousness.
