Prabhupāda: Now, if He is ordering to become His devotee, how can I try to become another God, competitor? This is the folly, and for this we are suffering. He asked him, "You become My devotee." And I want to become another God, competitor. And therefore we are suffering. We cannot become another God. That is not possible. But artificially you are trying. Therefore you are suffering. Anything you try artificially, you'll suffer. If you try for a thing artificially, then what is the result? Result will be suffering and disappointment. Therefore śāstra says, tasyaiva hetoḥ prayeteta kovidaḥ. Don't try for such things you have tried all through in different forms of life. You have failed. So don't try for that. But try to become servant of God. Then your life will be successful.
Because in the material world the endeavor is how to become God in different varieties: how to become president, how to become minister, how to become master, how to become very strong man, very wealthy man, very beautiful man, so on, so on, so on, up to—when everything fail—then how to become God. When everything fail, then, ultimately, "Now I shall become God." The same disease is there, how to become big, now the biggest. And that is the same disease in a different form. Therefore, Caitanya-caritāmṛta it is said, kṛṣṇa-bhakta-niṣkāma, ataeva śānta, bhukti-mukti-siddhi-kāmī śakali 'aśānta' (CC Madhya 19.149). Bhukti means material enjoyment. Karmīs . . . just like ordinary men, they are working so hard day and night. This aeroplane is running here and there, (loud airplane passing over) day and night, carrying karmīs. So this is bhukti. How to enjoy this material world fully, this is called bhukti.
So because they are after bhukti, how there can be peace? He has to work very hard. And mukti, those who are jñānīs, they are trying to become one with God. So that is also very difficult. But still, there are so many sādhanas. That is also . . . but the desire is there. The karmīs are desiring to enjoy material world, and the jñānīs are desiring to become the Supreme. That is also another desire. So bhukti mukti siddhi. Yogīs, they are trying to achieve some mystic power. If you attain some mystic power, without aeroplane if you can fly . . . the yogīs can do that. Or if you can walk on the water . . . the yogīs can do it. This is called laghimā-siddhi, to become light, very light. So that . . . by yoga practice you can do that. So animā, laghimā, siddhi, prāpti, mahimā—there are so many siddhis. So siddhi-kāmī, they are also desiring something. And the jñānīs, they are also desiring something, and karmīs, they are also desiring something. The bhakta, he does not desire anything. Therefore peacefulness is for him, because he does not desire anything. He does not ask God anything. That is śūnyam. Anyābhilāṣitā-śūnyam (Bhakti-rasāmṛta-sindhu 1.1.11)—no motive. That, "I am becoming a devotee for this purpose"—no, that is not pure devotee. "I am eternal servant of God, so it is my duty to serve Him, that's all." That is peace. And so long he'll desire, then he'll not have any peace. That is not possible.
