These Six Gosvāmīs, they were deputed by Lord Caitanya to discuss this science. They have written immense literature about it. You see? So you'll be surprised that they were sleeping only for one and half hour daily, not more than that. That also, sometimes they forego. You see? They are so much busy in spiritual activities, kṛṣṇotkīrtana-gāna-nartana-parau . . . so spiritual life is so sublime and so invigorating that you won't feel fatigued. Won't feel . . . once . . . you have to be engaged. And as you are engaged actually in spiritual life, you won't feel fatigued. You'll be fearless, and your life will be always blissful. These are the symptoms. So yogaḥ karmasu kauśalam (BG 2.50).
The Lord says that the . . . that this spiritual platform is the karmasu kauśalam. Kauśalam means expert service, expert, kauśalam. Kuśala. Kuśala means auspicious, and from kuśala it comes to kauśala. That means if you learn the trick how to work on the platform of yoga, then that is the highest technique of doing work. Buddhi-yukto jahā . . . and result of that work, what is that? Now, buddhi-yuktaḥ. When you work from the spiritual platform with your intelligence, then jahāti iha ubhe sukṛta-duṣkṛte. Sukṛta-duṣkṛta.
Now, for ordinary work, if you do good work, then you have to take good result. And if you do bad work, or sinful work, then if you have . . . you have to take the effect of such bad and sinful work. Sukṛta and duṣkṛta. But one who works from spiritual platform, he hasn't got to take the result of good work or bad work, because he is transcendental. He has no good work or no bad work. Everything transcendental work. Everything transcendental work.
That . . . just like take the example of Arjuna. He was thinking that, "Fighting of this nature is not good for me." That was his problem. And . . . because he was thinking on the bodily platform. The same Arjuna again took to fighting. Does it mean that by understanding Bhagavad-gītā he took to bad work? No. Just try to understand. He declined to fight. He thought that "Fighting for me with my relatives is not good." That was his conclusion.
