When Viśvāmitra Muni approached Mahārāja Daśaratha for help, taking Rāmacandra and Lakṣmaṇa for killing that rākṣasī . . . Viśvāmitra Muni could kill that rākṣasī, but because he was brāhmaṇa, it was not his business to kill. He begged help from Mahārāja Daśaratha to lend Lord Rāmacandra and Lakṣmaṇa, to take Him there. This is the systematic way. The brāhmaṇas should be engaged in knowledge and distributing knowledge. That means their business is not fighting. The kṣatriyas, they should fight. The killing business is meant for the kṣatriya. That is also required. Evam . . . cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13). The first of all . . . unless this division is there, that is animal society. That is not human society if these four divisions are not there. Varṇāśramācāravatā puruṣeṇa. Systematic human society means:
- varṇāśramācāravatā
- puruṣeṇa paraḥ pumān
- viṣṇur ārādhyate punsam
- nānyat tat-toṣa-kāraṇam
- (CC Madhya 8.58)
This is required, varṇāśrama. That is again confirmed here, evaṁ jñātvā kṛtaṁ karma pūrvair api mumukṣubhiḥ. Mumukṣubhiḥ. The real business is mumukṣā, how to get out of this business of repetition of birth. People do not know it. They do not know what is the aim of life. The aim of life is mumukṣā. This human life is meant for that, to get out of the cycle of birth and death. The animal cannot know this. Therefore it is called mumukṣubhiḥ, "One who wants to get rid of this business of repetition of birth and death." Mumukṣubhiḥ.
Kuru karmaiva tasmāt tvam. That is advice of Kṛṣṇa to Arjuna that, "You follow the previous ācāryas, previous personalities, authorities," just like svayambhūr nāradaḥ śambhuḥ, I have already described. "You follow them, and act like that, and you try to understand that what is My position. If you simply understand My position, immediately you become liberated." Janma karma me divyaṁ yo jānāti tattvataḥ, tyaktvā dehaṁ punar janma naiti. This is liberation. If you simply understand, try to understand Kṛṣṇa, why Kṛṣṇa comes, what is His instruction, why He says yadā yadā hi dharma, these things, if you simply understand, then you become liberated person.
And this is required in human life to be liberated. What is this nonsense business, sometimes human being, sometimes cat, sometimes dog? But they do not know. But this is a fact, that dehino 'smin yathā dehe kaumāraṁ yau . . . tathā dehāntara (BG 2.13). You have to change your body, transmigrate, but change for the better, or stop this change, go back to home, back to Godhead. That is required.
