So two words are there. One is singular number, nitya, eternal, and the other is plural number, nityānām. So we are plural number. Plural number eternals. We do not know what is the numerical strength of the living entities. They are described as asaṅkhya. Asaṅkhya means without any counting capacity. Millions and trillions. Then what is the difference between this singular number and the plural number? The plural number is dependent on the singular number. Eko bahūnāṁ vidadhāti kāmān. The singular number eternal is giving all the necessities of life to the plural number, we living entities. That's a fact, we can examine by our intelligence. 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. 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 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 beings—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 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. But one thing, although I cannot see you, you can hear me, or I can understand that you are hearing. The ears are stronger than the eyes. So things which is beyond our experience, we can hear about. Even though we cannot see, it does not mean there is no existence of things. The same example: even though I cannot see what is mind, what is intelligence, what is ego, but I can hear about it. Therefore perfect knowledge is acquired by hearing. So we accept knowledge, perfect knowledge, by hearing. Another example: suppose a man is sleeping. At that time, if somebody is coming to kill him, he's sleeping, he does not know. But if some of his friend warns him, "My dear Mr. Such-and-such, somebody is coming to kill you. Wake up!" he can hear, and he can wake up and take precaution. Therefore, when our other senses cannot work, our ear is very strong. Therefore it is recommended that you try to hear from the authoritative person. That is also... Educational system is also like that. Why do you come to university, school, and college? To hear from an experienced professor. He knows, and you acquire the knowledge by hearing.
So the process of hearing is very important. So our this Kṛṣṇa consciousness movement is to propagate that "You hear from the authority, Kṛṣṇa." Kṛṣṇa is the Supreme Personality of Godhead. It is accepted in the present age and in the past age. In the past age, great sages like Nārada, Vyāsa, Asita, Devala, very, very great stalwart scholars and sages, they accepted. In the Middle Age, say 1,500 years ago, all the ācāryas like Śaṅkarācārya, Rāmānujācārya, Madhvācārya, Nimbārka... Practically, Indian Vedic civilization, it is still existing on the authority of these ācāryas. And it is recommended in the Bhagavad-gītā: ācāryopāsanam. If you want to learn factually things, then you should approach ācārya. Ācāryavān puruṣo veda, "One who has accepted ācārya, he knows things as they are." Ācāryavān puruṣo veda. So we are receiving knowledge through the ācāryas. Kṛṣṇa spoke to Arjuna, Arjuna spoke to Vyāsadeva. Arjuna actually did not speak to Vyāsadeva, but Vyāsadeva heard it, Kṛṣṇa speaking, and he noted down in his book Mahābhārata. This Bhagavad-gītā is found in Mahābhārata. So we accept the authorities of Vyāsa. And from Vyāsa, Madhvācārya; from Madhvācārya, so many disciplic succession, up to Mādhavendra Purī. Then Mādhavendra Purī to Īśvara Purī; from Īśvara Purī to Lord Caitanyadeva; from Lord Caitanyadeva to six Gosvāmīs; from six Gosvāmīs to Kṛṣṇadāsa Kavirāja; from him, Śrīnivāsa Ācārya; from him, Viśvanātha Cakravartī; from him, Jagannātha dāsa Bābājī; then Gaura Kiśora dāsa Bābājī; Bhaktivinoda Ṭhākura; my spiritual master. The same thing, we are preaching. That is Kṛṣṇa consciousness movement. It is nothing new. It is coming down from the original speaker, Kṛṣṇa, by disciplic succession. So we are reading this Bhagavad-gītā. Not that I have manufactured some book and I am preaching. No. I am preaching Bhagavad-gītā. The same Bhagavad-gītā as it was first spoken forty millions of years ago to the sun-god and again it was repeated five thousand years ago to Arjuna. The same thing is coming down by disciplic succession, and the same thing is presented before you. There is no change.
