So to kill a demon in this material world, the Lord does not require to come Himself. But He comes in special case, just like Kṛṣṇa came to kill Kaṁsa, to kill Rāvaṇa, to kill Hiraṇyakaśipu, like that. So that is also His pastime.
So His devotees are also like that. They have to execute the mission of Kṛṣṇa. Just like here, Parīkṣit Mahārāja, he is a great devotee of Kṛṣṇa. So he is going out with soldier to fight. Similarly, Dhruva Mahārāja also, he fought. Prahlāda Mahārāja fought. Because they were kings, so their duty is to subdue, to conquer over the demons. Not that because one is Kṛṣṇa devotee, he should not do any other thing. If required, a devotee can do anything, as ordered by Kṛṣṇa, as Kṛṣṇa ordered Arjuna to fight. Arjuna personally was not inclined to fight. He is Vaiṣṇava. He, rather, wanted to forgive, "Let them enjoy, Kṛṣṇa. I do not wish to fight with my cousin-brothers. I cannot tolerate their death, my grandfather. So better I will not fight. Let them enjoy the kingdom." So Kṛṣṇa said: "No, that cannot be. It is My plan that they should be killed. So you must fight." So therefore a devotee's duty is to carry out the order of Kṛṣṇa. Therefore he fought. Personally he did not want to fight. But he cannot disobey the order of Kṛṣṇa. That is not possible. Kariṣye vacanaṁ tava (BG 18.73). When Kṛṣṇa inquired, "What is your decision?" he said: "Yes, even though I do not like to fight, still, because it is Your order, I must fight." Kariṣye vacanaṁ tava (BG 18.73).
So devotee hasn't got any personal decision. That is the process of Kṛṣṇa consciousness. Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). We should decide by the order of Kṛṣṇa through the disciplic succession, via media, the spiritual master. That is required. A devotee cannot decide personally. If Kṛṣṇa desires . . . if somebody says that, "We cannot see Kṛṣṇa personally," then you have to decide by Kṛṣṇa's representative. If your spiritual master, guru, says that "You do this," that is Kṛṣṇa's order. That is Kṛṣṇa's . . . therefore it is said, yasya prasādād bhagavat-prasādaḥ. By satisfying the spiritual master, you satisfy the Supreme Personality of Godhead. That is very natural. Just like when you go to your work, the immediate person who is in charge of your work, he must be satisfied. You don't jump up to the proprietor. The proprietor will be automatically satisfied. If something is done and the proprietor sees that the immediate office superintendent is satisfied, then he accepts, "Yes, that's all right." He hasn't got to inspect personally. If the superintendent of the office says that, "Yes, this clerk or this man works nice," then proprietor accepts. Similarly, yasya prasādād bhagavat-prasādaḥ. We have to satisfy our spiritual master, sevayā.
