Everything is coming out of the womb of the mother. Whatever we see in this creation—the plants, the trees and living entities, and we are speaking especially of the living entities, and there are 8,400,000 different forms—they are coming from earth. That we can see. It doesn't require great intelligence. Any boy can understand that it is coming out of these five elements—means earth, water . . . The grass is coming out of earth, the fish is coming out of the water. So we have got experiences in two elements. But we have got experience also that living entities coming out of air. So earth, water, air . . . There are living entities in fire also, but because our knowledge is limited, we do not see. We cannot conceive that in the fire also there can be living entities. And why not? There are five elements, matter. So if earth is producing life, if water is producing life, if air is producing life, why not fire? What is the fault there? Everything is producing life.
So the mother produces children. So many children are coming out of the . . . Tāsāṁ mahad yonir brahma (BG 14.4). Yoni, yoni means mother. So the children are there, the mother is there, and where is the father? A commonsense. Is there any mother can produce children without father? Is there any science can prove that a mother without connection with the father has produced child? No. If you say, "I cannot see the father," you do not see your fathers, there are many children nowadays who do not know who is father. But that does not mean there is no father. Common sense. There is father. Similarly, we see so many living entities produced by the mother, material nature—there must be father. And the father personally says, ahaṁ bīja-pradaḥ pitā (BG 14.4)—"I am the father." So why these rascals, they say that there is no God? There must be God, and He has got inconceivable potencies. Everything is being done by Him. If you say nature is doing, nature is a machine. Nature is not the doer. Mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10).
So less intelligent, for them, it is inconceivable, but those who are intelligent, they take knowledge from the right source. Just like even though I do not know who is my father, but if I take information from my mother, then I can know. Mother says, "My dear child, he's your father," there's no question of research. You can immediately understand your father. Father must be there. But I do not know, that may be a problem, but when the mother says, "Here is your father," then where is the difficulty? So mother is the source of knowledge of the father. The Vedas, they are called mother. Veda-mātā. These books, Vedic knowledge, this is the mother. From mother you can take information that there is father. And here is father. Who is father? Kṛṣṇas tu bhagavān svayam. Ete cāṁśa-kalāḥ puṁsaḥ kṛṣṇas tu bhagavān svayam (SB 1.3.28). Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda (BS 5.1). And the father comes personally and He informs, mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya (BG 7.7), ahaṁ bīja-pradaḥ pitā (BG 14.4). Then where is the difficulty? Is there any difficulty? But because we are rascals, we'll not believe mother, we'll not believe father. We, with our tiny brain, we shall make research and make things topsy-turvy and pass on as great scientist, doctor. This is our position. Therefore śāstra says that "You rascals, do not waste your time in that way." Acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yojayet (CC Adi 17.308, Mahābhārata, Bhīṣma parva 5.22).
So according to Vedic system, the difference between atheist and theist is that the atheist means who do not believe in the version of the śāstra. Yaḥ śāstra-vidhim utsṛjya vartate kāma-kārataḥ na sa siddhim avāpnoti (BG 16.23). So our this Kṛṣṇa consciousness movement is not blind. Don't think wrongly. We are confident. We sometimes challenge big, big scientists. On what ground? Not whimsically, but on the ground of śāstra. So we may not please everyone, but we cannot go out of this scope. We know that in the moon planet, in the Mars planet and all other planets, Jupiter and others, there are living entities, there is a predominating deity in each and every planet. Just like Kṛṣṇa says, imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1). So if there is no living entity in the sun planet, how there is Vivasvān, the sun god, or the predominating deity in the sun planet? So we cannot believe this version that there is no living entity in the sun, moon, or . . . There are living entity, full of, jana-kīrṇa, this word is used. Congested. Just like here in this planet we are congested: so many living entities, different varieties. Similarly, the same congestion is there in all other planets. So do not try to poke your nose which is inconceivable. And that also not assertion. You say "Perhaps," "Maybe," "Millions of years," "It might have been." All suggestion. So if you want knowledge, then you have to consult this Vedic knowledge. Veda means knowledge, the source of knowledge. That is called Veda. And the ultimate knowledge is Kṛṣṇa. Vedaiś ca sarvair aham eva vedyam (BG 15.15). That is the version.
What is the use of studying Vedas? To understand Kṛṣṇa. So if you simply understand Kṛṣṇa, then you understand everything. Try to understand Kṛṣṇa thoroughly. And if you understand Kṛṣṇa thoroughly . . . Of course, it is not possible thoroughly, but it is possible also. Just like Kṛṣṇa is the source of everything. So if you believe it, it is understanding thoroughly. If you believe that what Kṛṣṇa says is fact, then it is understanding thoroughly. If you don't believe, then it is not thoroughly. Because if you make research that "Kṛṣṇa says, 'I am the origin of everything.' Let me make research," that will not be possible. Inconceivable. But if you believe in the words of Kṛṣṇa, then you've studied thoroughly. Where is the difficulty? To study thoroughly does not require much education; simply you believe Him. And if you believe Him . . . Actually, that is the fact. There must be . . . Just like the same example: there must be a father of all this creation. Mother nature is mother, and we are all creation, born of material nature. Then there must be father. And when the father says, ahaṁ bīja-pradaḥ pitā (BG 14.4), "I am father," then if we believe this version, then thorough knowledge. Father, mother, children. That is family, creation.
