Nārada Muni created this, thinking of the poor people of this age without perfect knowledge. Why this education is required? Because naiṣkarmyam, without producing fruitive result. What is that work? Any work you do, there must be some result. Either you do good work or bad work, it . . . there is work, there must be some result. That is our experience. We cannot do anything which has no result. But if that result is offered to God, Kṛṣṇa, then it is without result.
So that work is not stopped. Just like Arjuna. Arjuna's work was not stopped. He was a fighter; rather, he wanted to stop his work. He said: "My dear Kṛṣṇa, what is the use of fighting? They are all my kinsmen; let them enjoy. I don't want this kingdom." He wanted to become a gentleman without working. No. That without working is work, because he was considering in his own terms. But when he fought on the advice of Kṛṣṇa, that is naiṣkarmya—without result. Because fighting, suppose Arjuna has killed so many persons, so he is supposed to be under so much tribulation because he has killed so many persons. But because that was done for Kṛṣṇa, that is naiṣkarmya—no result; means work which does not produce any reaction. Other work, just like in this life those who are working for sense gratification, they are creating another body.
So it is not fruitless. If you work piously, then you create next life. Life is continuous. We are simply transmigrating from one body to another.
