In plain words
Bhakti alone is the royal road to the highest goal. The Name of God alone is the divine medicine that cures the ills of birth, death and the rest. Neither machines and contrivances, nor missiles and weapons, nor politics can protect the country. Faith in God, sacrifice, a spiritual outlook: these alone can safeguard the country. So, if peace and security are to be brought to the country, women and men must cultivate all these three. From ancient times Bhārata has been giving such sacred spiritual teachings to all the nations. Bhāratīya culture is that very thing which fosters the brotherhood of all mankind, brings about harmony, makes equality manifest and bestows Ānanda. But today many are trying to hide the true nature of this culture; not following so sacred a culture, they fall prey to unrest and go through many hardships. In man today attachment to the body has grown and love of the country has shrunk; the practice of creed has grown, and the practice of the Supreme has shrunk. Through losing faith in God, the human values in man have wasted away; love of God and fear of sin have grown thin; the very spirit of sacrifice has come to nothing. Statecraft joined to the spirit of sacrifice, and love of God joined to the feeling of Prema: these man needs most urgently.
No one knows at what time, for what reason, God will perform what act. God's daily acts, His reasons and His duties are, every one of them, teachings in themselves! It is not only when He gives a discourse by way of teaching; whatever He says is itself a teaching. What is more, God shows no mercy or leniency at all in the tests He sets; He sets hard tests. “Will sugarcane give jaggery for the calling and asking, unless you beat it to pulp and draw out its juice?” Our body itself is like sugarcane. Only when it is put to pain and testing in many ways does the sweetness called divinity come from it. But many fail to recognise this truth and lament, “Why is God testing me like this?”
Karṇa's devotion to sacrifice
On the fourteenth day of the Mahābhārata war Karṇa fell to the ground, and the Pāṇḍavas were swelling with joy. Noticing that Kṛṣṇa alone sat there very sad, Arjuna asked, “Brother-in-law! At a time when you should be full of joy, why do you look so sad?” Kṛṣṇa, “Arjuna! There is no other so given to sacrifice as Karṇa. I grieve that the country today is losing such a great soul, such a man of sacrifice,” He said. Some doubt arose in Arjuna. “Is there no one else in this country greater in sacrifice than he?” he asked. Kṛṣṇa, “In My view, at any rate, there is none greater in sacrifice than Karṇa. If you want proof of this, come with Me,” He said.
Disguised as brahmins, Kṛṣṇa and Arjuna went searching over that battlefield, wrapped in pitch darkness, calling, “Karṇa! Karṇa!” And Karṇa, who in a few more minutes was to give up his life, “Who are they?
