There are two condition of life. Actually, conditioned life and non-conditioned life, liberated life and conditioned life, that is real nomenclature, liberated life and conditioned life. Conditioned life means this material world. We are conditioned by the laws of material nature. Just like we are trying to go to the moon planet, but we are conditioned; we cannot go. There are so many impediments. This is the nearest planet. Still, because we are conditioned, we cannot go. No free access. Otherwise, a living entity name is sarva-ga. Sarva-ga sthāṇur acalo 'yam (BG 2.24). Sarva-ga means a living entity can go anywhere. As we see, there are so many planets. Why we cannot go? There are means also. We are flying in the air, but we cannot go. This is called conditioned life. There are so many instances. Just like even on this planet if you want to go to other countries, say, America, you have to fulfill so many conditions—passport, visa, then P-form and so many other forms. Not easily. This is called conditioned life. We have no freedom to move.
And there is another life, which is life of freedom. 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.
