Just like Nārada Muni. Nārada Muni travels everywhere. He goes in the spiritual world; he comes in the material world. In the material world he can go in any one of the planets. Sometimes by yogic practice we can go also, but not so easily. So there is a life of freedom. That is spiritual life. Nitya-mukta, the living entities who are living, who are residing in the spiritual world, their number is greater than the conditioned soul. Just like some of our friends or citizens, they are in the jail. Their number is not as many as there . . . we are free. Similarly, the number of free living entities in the spiritual world is greater than the number of the conditioned souls. A few only, we are conditioned. And this conditioned means karmāṇi. Karmaṇā daiva-netreṇa jantur dehopapattaye (SB 3.31.1). As we are doing work, fruitive activities, under the influence of a particular type of modes of nature, we are getting different types of bodies, and there are 8,400,000's forms of bodies, and we are rotating. Because we do not know, we have forgotten how to become free from this cycle of birth and death and transmigration of the soul. This is called karma. Yajñārthāt karmaṇo 'nyatra loko 'yaṁ karma-bandhanaḥ (BG 3.9). Therefore in the human form of life we must perform yajña. Yajña means to satisfy the Supreme Lord. Yajñārthe, for the sake of the Supreme Lord, for satisfying Him, that is our business.
So to do that business, in the previous verse it has been prescribed that the human society should be divided into four classes of men. There are, but they should be systematically divided. Just like in any office there are departments. Without departmental work, nothing can be successful. Anywhere you go, either in the law court or in the office or anywhere, there must be department. Similarly, the human society must be divided into four divisions. Not four division—eight divisions, varṇāśrama.
In the Vedic literature there is no such thing as Hindu dharma or Muslim dharma or Christian dharma or Buddha dharma. These are recent manufacture. Actually, Vedic instruction is to divide the whole human society into four varṇas and four āśramas. That is Vedic dharma, sanātana-dharma. It is called sanātana-dharma. A living entity has got the chance of getting this human . . . labdhvā sudurlabhaṁ bahu-sambhavānte (SB 11.9.29). Bahu-sambhavānte means after many, many births. This present rascal civilization does not know that how with great difficulty we have come to this human form of life after so many evolutions. The Darwin's theory of evolution, there is some idea, but it is not clear, not scientific. They are trying to prove that scientific; that is not scientific. But the evolution theory is there, 8,400,000's species of life, jalajā nava-lakṣāṇi sthāvarā lakṣa-viṁśati (Padma Purāṇa), like that. Bhramadbhiḥ. We are rotating in this way.
