Out of 8,400,000 different forms of life, we civilized human beings are very few. But others, their number is very great. Just like in the water: jalajā nava-lakṣāṇi (Padma Purāṇa). There are 900,000 species of life within the water. Sthāvarā lakṣa-viṁśati: and 2,000,000 different forms of life in the vegetable kingdom, plants and trees. Jalajā nava-lakṣāṇi sthāvarā lakṣa-viṁśati, kṛmayo rudra-saṅkhyayaḥ: and the insects, they are 110,000's different species of form. Kṛmayo rudra-saṅkhyayaḥ pakṣīṇāṁ daśa-lakṣaṇam: and birds, they are 1,000,000 species of forms. Then beasts, paśavas triṁśa-lakṣāṇi, 3,000,000 types of animals, four-legged. And catur-lakṣāṇi mānuṣaḥ, and the human being, the forms are 400,000. Out of them, most of them are uncivilized.
So we civilized human being—never mind American or Indian or German or Englishman, it doesn't matter—we are very few. So we have got economic problems. We are trying for developing our economic condition. What is that economic condition? Eating, sleeping, mating and defending. We are busy always, but the animals are also busy for eating, sleeping, mating and defending, but they have no problem. We have got problems.
So just try to understand, if the major portion of the living entities have no problem . . . their necessities of life are being supplied by the supreme eternal, God. Just like an elephant. There are millions of elephants in African jungle. They eat at a time fifty kilos. But they're getting their food. Similarly, a small ant, it requires a grain of sugar. So he's also getting his food. So the supreme eternal has arranged food, or the economic problems are solved by nature. They do not do any business, they do not go to school or colleges to learn technology, to earn livelihood, but they are being supplied. They are healthy. There is no disease.
So our advancement of civilization means we have created problems. That's all. This is our advancement of civilization, and we do not know what is the formation of the soul, how it is transmigrating from one body to another, what is the next life, whether we are getting next life a human being or better than human being or lower than human being. And if it is so, how we are getting that form of life next? Because we are eternal; we are changing this body. Neither we do know there are two kinds of bodies: the gross body and the subtle body. This gross body is made of earth, water, fire, air, ether; and the subtle body is made of mind, intelligence and ego. Within the subtle body, the soul is there.
Now, when this gross body becomes useless or unworkable, then the subtle body carries me to another gross body. This is called transmigration of the soul. But we do not see the subtle body. Every one of us, we know that we . . . we have got mind, but we cannot see the mind. Neither we can see intelligence, neither I can see what is my ego. But they are existing. So it is not necessary that everything you have to see with your blunt eyes. The eyes, they are not perfect. Just like the other side of this hall is dark; I cannot see you, although I have got the eyes. So even though we have got eyes, it is very imperfect. It cannot see in all circumstances. Under certain circumstances we can see. Therefore we should not believe simply by seeing.
