We take things very insignificantly, "Ah, by nature," but you cannot explain what is nature. In the garden you see different flowers are coming out. The same ground, the same water, but different flowers are coming out, different flavor, different color, all different, varieties. So the answer is bījo 'haṁ sarva-bhūtāni (BG 7.10). He is the seed. He is the seed. You have seen the banyan tree, a small seed. But this small seed has got so potency that if you sow it in a nice place and water it, one day it will come a big banyan tree. Now, what are the potencies, what are the artistic arrangement, scientific arrangement, within that small seed that it grows a big banyan tree? Not only a big banyan tree, but also many millions of big fruits, and within each fruit there are millions of seeds, and each seed contains the potency of another tree.
So where is your science in that way? Where is that artist within this material world? Where is that pleasure of that artistic work? These things should be enquired. Athā . . . it is called athāto brahma jijñāsā. In the Vedānta-sūtra this is the first aphorism that, "In the human form of life these enquiries should be made. These studies should be made." This is a fact. You cannot manufacture such machine that automatically a rose flower is coming out. You cannot make a chemical combination or a tablet which contains a big banyan tree automatically will come out.
