In plain words
On the field of fury and on the field of peace alike, Arjuna wanted no strength other than the presence of Kṛṣṇa, the Ānanda of Kṛṣṇa and the strength of Kṛṣṇa. Though, human nature being what it is, a little Ahaṅkāra raised its head now and then, he would remember Kṛṣṇa and say, "Kariṣye vacanaṃ tava: I take Your command on my head and do my part in my work." "I am one who takes Your command on his head, never one who breaks it," he said. That is why:
Fix your mind on Me, be devoted to Me, worship Me, bow down to Me; you will come to Me alone; I promise you truly, for you are dear to Me.
"Arjuna, now you are My devotee. Not only a devotee. You are My friend," He said. Such a one, a supreme devotee and a friend, was Arjuna. The one who taught that to win friendship with God is the chief path in the world was Arjuna.
Now the ninth is ātmanivedanaṃ. He is the hero of today's story. He is the chief figure of this sacred day. He is Emperor Bali. O God! What is there in me? You are everything: with this feeling of self-offering, the one who offered himself up was Emperor Bali. Vāmanamūrti is calling Emperor Bali with love. Come! O son of man! Rise; whatever You wish I will give, never saying no. O! Vāmanamūrti, come. O great soul! Give Your feet into my hands. I shall wash Your feet and keep the water of Your feet on my head. Śukrācārya was a brahmin who knew everything. He was Emperor Bali's priest. A great scholar. He was the one who recognised that Vāmanamūrti was the very form of Viṣṇu. But "You must not stand ready to give what he asks," he urged Emperor Bali earnestly. It is Śrī Mahāviṣṇu Himself who has taken this form and come to you with His hand stretched out. He is Trivikrama. He can take away everything. "So do not give what he asks," he urged. Think well how great a heart Emperor Bali had! God Himself, in person, stretching out His hand: "Emperor Bali! Give!" When He asks this, my hand, the hand of a lowly man, stands above the hand of the Paramātma; what greater good fortune could I want than this? God's hand below, my hand above: this itself is the great good fortune. "Come what may, I will offer up everything," he said, and refused even his guru's command. On the path to God, whoever it may be, refuse him: so the Veda has taught.
Mātṛdevo bhava. Pitṛdevo bhava. Ācāryadevo bhava. These are the chief precepts in the śāstras of Bhārata. But when it comes to a matter that parts you from God, refuse even your mother: so Bharata refused Kaikeyī and went away. Though his father commanded him not to think of Hari, Prahlāda refused his father's command and merged in the thought of Hari.
