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.
So yato 'ato brahmaṇas tās tu sargādyā bhāva-śaktayaḥ (Viṣṇu Purāṇa 1.3.2). So this creation is another. Just like children is creation of the semina of the father, similarly, the whole thing is creation of the Absolute Truth. And the example is given: bhavanti tapatāṁ śreṣṭha pāvakasya yathoṣṇatā (Viṣṇu Purāṇa 1.3.2). The fire, the fire must have heat, and by heat you can create so many things. In the Western countries, the electricity . . . What is electricity? It is heat. So heat . . . Through electricity so many things are being created, through electric energy. The heat is created and the cool is also created. The refrigerator is going on by electric current, and heater is also going on. Two contradictory, but still, the energy is the same. Similarly, viṣṇu-śaktiḥ parā proktā (CC Madhya 6.154). It is, we have already described, Viṣṇu, Lord, the Supreme Lord, all-pervading, His energy is also spiritual. But when we cannot understand it, that is material. Otherwise, the energy . . . Just like electricity. The electricity is working in the refrigerator—it is cool. So therefore in the refrigerator there is no appreciation of the heat, although heat is there. But in the heater there is direct appreciation. But the energy is the same.
So material means when we do not understand Kṛṣṇa, when we do not appreciate His creative energy or when we are in ignorance. That is called material life. So all these fools and rascals who are unaware of Kṛṣṇa's energy, they are all fools and rascals. That is stated in the Bhagavad-gītā: na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ. Therefore we have taken it very easily. Because we are not very advanced scientists, we take the words of Kṛṣṇa.
