Just like the symptoms of life means it takes birth at a certain date, then it grows, it stays, it gives some byproducts, then dwindles, then vanishes. Take any. Either you take tree or you take a human body, or you take an animal body or if you take an insect body, or take the demigod's body—any body you take, there is a certain date of birth, everyone, certain date of birth. And then there is a certain duration of life. Somebody lives for ten years. Somebody lives for one year. Somebody lives for six hours, five hours. There are many germs. They live for five hours, six hours, or even less than that. And there are living entities like Brahmā, whose life is millions and millions of years.
There are so many varieties of life. We have no information. There are so many universities, so many educational institutions, but they cannot say exactly how many varieties of life are there. They cannot say. Their education is not perfect. They cannot say. But we can see there are so many varieties of life, and each of them is a living entity. But if you consult Vedic literature, you'll find exactly the number. Just like in the Vedic literature you'll find jalajā nava-lakṣāṇi: "In the water the aquatic living beings are 900,000 different bodies." So I don't think there is any biologist or botanist who can say exactly how many forms of life are there within the water.
But you'll find the information exact in number, jalajā nava-lakṣāṇi: "The aquatics, the living entities within the water, there are nine hundred thousands 900,000's of forms." We have got information from Vedic literature. There is a fish which is called timiṅgila. Timiṅgila. Timi means... Timi is also another fish. That is Sanskrit name. The English name is whale fish. It is very very big, just like one small house. And there is another fish which is called timiṅgila. These timiṅgila fish swallow up these whale fish like, like this. (laughter) Such a big fish. These informations are there. Therefore try to understand how much perfect knowledge is there in the Vedas. So similarly, right information is there.
