Any learned scholar cannot make any injustice. So he admitted his defeat, because he is learned scholar. That is scholarship. Not that . . . just like Sarvabhauma Bhaṭṭācārya. He argued with Śrī Caitanya Mahāprabhu as a scholar. But when he became defeated, he accepted His discipleship. This was the method, that two persons may argue, but one who is defeated, he must become his disciple. Not that simply waste time arguing and no conclusion. Formerly this was the system, to come to a conclusion. If two parties are arguing on a subject matter, the one party will be defeated, he must become his disciple, under control.
So here the same digvijaya. Digvijaya, for learned scholar, by arguing on śāstra, that is another kind of digvijaya. And digvijaya for kṣatriya, by subduing others who do not accept the authority. So here Parīkṣit Mahārāja went for digvijaya just to challenge all over the world, "Now I have been selected by my grandfather as the emperor of the world. If you do not accept my authority, then here is fight. Come on. Here is fight. Let us fight." So if by fight he becomes victorious . . . just like in modern sporting also, there are rival parties, and ultimately, the party which defeats all other sportsmen, they get some reward, seal, or some cups. Similarly, this is also another type of digvijaya. Parīkṣit Mahārāja went out of home, not king simply drinking and enjoying the dancing of the young girls just like the Muhammadan kings when they deteriorated. Still there are so many fools. No. King's duty is to subdue the miscreants who will create disturbance. So Parīkṣit Mahārāja was such a nice, what is called, hero, that he got out of his home. Sva-senayā digvijayāya nirgataḥ. Nirgataḥ means went out of home, not simply enjoying comfortably at home. Similarly, for a preacher also, that is digvijaya. Go from country and country, from village to village, town to town, and make digvijaya, "Here is our philosophy. There is God. We can prove there is God. Who are you, you deny God? Come on." That is digvijaya.
