Now here Kṛṣṇa is advising. So ānukūlyena kṛṣṇānuśīlanam. There is a . . . parīkṣatā, as Kṛṣṇa is examining, similarly, Arjuna also very intelligently acting. He knew that although Kṛṣṇa was encouraging him to kill Aśvatthāmā, "He wanted to see me, how I deal with the matter." This is also . . . there is competition between bhaktas. Dui lagye hura huri, it is stated in the Caitanya-caritāmṛta. Between Rādhā and Kṛṣṇa, Kṛṣṇa is being enlivened by seeing Rādhārāṇī, and Rādhārāṇī is becoming more beautiful by seeing Kṛṣṇa. Dui lagye hura huri, the competition. This is described in the fourth chapter of Caitanya-caritāmṛta. So it is transcendental sporting between the devotee and the Lord. It is not nirviśeṣa-vāda. The Lord wants to see, "How he is My pure devotee." And the devotee wants to see that "I'll not accept anything from Kṛṣṇa. I shall sacrifice everything for Kṛṣṇa." That is dui lagye hura huri. That is devotee, and that is Kṛṣṇa.
So here is Arjuna. He's being examined by Kṛṣṇa. Kṛṣṇa wants to examine His devotees, how staunch devotee he is. Just like the Pāṇḍavas. They were put into so many troubles. They lost their kingdom, they lost their wife—insulted. The wife was endeavored to become naked. Never, the Pāṇḍavas never said that "Kṛṣṇa, You are our friend. Why we are suffering so many troubles?" Never. Never. This is pure devotee. Kṛṣṇa is always with him. Kṛṣṇa could do anything, but still they never requested, neither Kuntī nor Pāṇḍavas. This is pure devotion. A pure devotee will never try to take anything from Kṛṣṇa. He will try to give everything to Kṛṣṇa. So dui lagye hura huri. So here is a trial between the devotee and Lord Kṛṣṇa, and Arjuna has passed the examination. Therefore it is said, evaṁ parīkṣatā dharmaṁ pārthaḥ kṛṣṇena coditaḥ. He's being examined by kṛṣṇena, not ordinary person. But he passed the examination. Why? Naicchad dhantuṁ guru-sutam. In spite of Kṛṣṇa's, I mean to say, injection that "Do it," he did not like to do it. Naicchad dhantuṁ guru-sutaṁ yadyapy ātma-hanaṁ mahān—although he is the greatest criminal.
