So when a human becomes jijñāsu, inquisitive, śreya uttamam... Śreya means ultimate goal of life, and uttamam... Uttamam. Tama means darkness. Tama means darkness. Not in the darkness, but uttamam. Udgata-tamaṁ yasmāt. When he transcends this darkness field of activities... Tamasi mā jyotir gama: "Don't remain in the darkness activities. Come to the light activities." So when one becomes inquisitive for the light activity, he is human being. He's called jñānī. The karmīs, they are in darkness. Their activity has no meaning. The other day we have discussed, vyartha-karmabhiḥ. Vyartha-karmabhiḥ. Vyartha means futile, useless. The karmīs, they are thinking very busy. If you go to see a karmī, he will say, "Oh, I have no time." "What you are doing, sir?" "No, I am very busy. I am earning money." So... But śāstra says, "You are simply wasting your time." Vyartha-karmabhiḥ. Vyartha-karmabhiḥ. The karmīs, they are working simply for useless result. How useless result? Because you have to change your body. Tathā dehāntara-prāptiḥ (BG 2.13). That is a fact. You believe or not believe, you are changing your body every moment. So simply you have no eyes to see, you have no brain to understand. You may be... Because you are cat and dog, you cannot understand. Because the cats and dogs, they cannot understand that there is another life after this dog's body and cat's body. They cannot understand. So anyone who cannot understand the simple truth of the transmigration of the soul, he is no better than this cat and dog.
So these karmīs are like that. Some of them understand. They at least believe in future life. But they do not know how to stop this transmigration of the soul. That they do not know, karmīs. They know, "It is unavoidable to change the bodies. So there is no need of endeavoring..." Therefore they do not know, they cannot know, neither they can do. They simply, "Yes, there is life, but let me become in more comfortable situation." Just like in this life, they are trying just to become in comfortable situation of this body, similarly, when they understand that, accepting at least that there is next life, they want to go to the heavenly planet, svarga. But they do not know that that is also not ultimate happiness. That is stated in the Bhagavad-gītā. You read nicely. Ābrahma-bhuvanāl lokāḥ punar āvartino 'rjuna (BG 8.16). Because even if you go to the Brahmaloka, the highest planet, either by good work or by your airplane sputnik... It is not possible to go there by sputnik (laughter), but you can go there by your pious activities. Yānti deva-vratā devān pitṟn yānti pitṛ-vratāḥ. Yānti (BG 9.25), you can go, but you have to adopt a means. But these are for the karmīs, those (who) simply want comfortable life of this body. They cannot understand that "However comfortably I may live, I have to give up this body. Then what is my next position?" They do not know. They are called karmī.
