And the society, the human society, not the animal society. Kṛṣṇa says: cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma (BG 4.13). Guṇa-karma-vibhāgaśaḥ. So according to guṇa, if we are associated with sattva-guṇa, then that class is called brāhmaṇa. If one is associating with rajo-guṇa, that class is called kṣatriya. If one is associating with mixed guṇa, especially rajo-guṇa and tamo-guṇa, that class is called vaiśya, and if one is associating with tamo-guṇa, that class is called śūdra. Cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). So in this way, there are varieties of life.
But that opportunity is given by Kṛṣṇa. Because He's witness. He is anumantā, upadraṣṭā. He's seeing everything. He is within our heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (BG 18.61). So in this way we are changing different varieties of life... Sometimes human being, sometimes animal, sometimes demigod. Sometimes something else. Sometimes rich man, sometimes poor man, sometimes brāhmaṇa, sometimes śūdra. In this way, we are wandering in different species of life, and different position, in different planets. There are millions and trillions of planets. And there are eight million, four hundred thousand species of life. In this way, we are wandering. this is our position.
So this is not very good business. Bhūtvā bhūtvā pralīyate (BG 8.19). We accept... Just like we have got this now human form of body, Mr. Such-and-such, very good position, very good business, very good... But at any moment, I'll be kicked out. At any moment. That is no guarantee. And again I'll have to accept according to my karma, another body where I may not get this position. I may be... I may not be even human being. Because, according to my mentality, I'll get the body. Yaṁ yaṁ vāpi smaran loke tyajaty ante kalevaram (BG 8.6). Our next birth will be settled according to the mental condition at the time of death.
So that mental condition one has to practice. What kind of practice? That is also, how the practice should be done, that is also indicated in the Bhagavad-gītā: yānti deva-vratā devān pitṟn yānti pitṛ-vratāḥ (BG 9.25), They are trying to go to the moon planet, but you cannot go in that way. That is not possible. You cannot go by force in any planet. You have to prepare yourself. Just in this planet also, if you want to go to some other country, in America, you have to prepare yourself for passport, visa, and what... So many papers. Pink forms. And bank balance. This, that, so many things. You cannot by force, that "I have come to America..." The immigration department will immediately check: "Where is your passport? Where is your visa? Where is your bona fide?"
Similarly, if such rules and regulations are here, even in this planet, how you dare to go into the moon planet or other planet by force? This is all childish. Now they have stopped. The American government has stopped financing this foolish excursion. Going to the moon planet. They have stopped. They have now come to sense that simply these so-called scientists, they're experi, experimenting on public money and wasting.
Long, long ago, when I wrote my book, Easy Journey to Other Planets, I described: "This moon planet excursion, simply childish and foolishness." And about two, three years ago, in San Francisco the press reporters asked my opinion about the moon, moon planet. So I told them: "it is simply waste of time and money." Now, now it is happening. Long, long ago, I said this. This is not possible.
Although there are innumerable planets, but even if you go to the moon planet, your problem is not solved. What is the benefit? If you... Suppose if you go to moon planet. How your problem is solved? The real problem is that I am forced to accept different types of body. Janma-mṛtyu-jarā-vyādhi (BG 13.9). And as soon as I accept body, I have to be under the tribulation of material nature.
That was advised by Ṛṣabhadeva: nūnaṁ pramattaḥ kurute vikarma (SB 5.5.4). All these foolish rascals, being mad, they're acting against the laws of nature. Vikarma. Vikarma means against the laws of nature. That is vikarma. Karma means prescribed duties. And akarma means doing something which will have no effect. Three things are there. Karma, vikarma, akarma. Karma means prescribed duties. If you want... Just like you want to do business, you must do according to the rules and regulations, license of the government. Then you make profit, be happy. That's another thing. But if you act vikarma, against the rules and regulations of the state, you commit theft or this or that, then you'll suffer. Vikarma.
And akarma means you act in such a way that you become liberated. Akarma. You are not bound up. That akarma is yajña, yajñārthāt karmaṇaḥ anyatra karma-bandhanaḥ (BG 3.9). If you act for Viṣṇu or Kṛṣṇa, then you are not, I mean to say, liable of the responsibilities of karma. Because you are doing everything for Kṛṣṇa. Just like Arjuna did. Arjuna was thinking that "If I kill my grandfather, the other side, then I shall be merged into the sinful activities. He's my superior. He's my guru. And he's my..." In this way, he was thinking. Actually it was so. So he was declining to fight. Because that was karma. But when he decided to fight on the order of Kṛṣṇa, that is not karma. That if there is any sin, that is... It may be transferred to Kṛṣṇa.
