In plain words
We must make all the senses given to man flow along the right road.
Among the sacred histories of Bhārata, the Rāmāyaṇa, the Bhāgavatam and the Mahābhārata are most exemplary books. Man does not try to recognise the ideals in them. He listens. He gives talks. He teaches them himself. But he does not try to grasp their inner meaning. Rāvaṇa of the Rāmāyaṇa is kāma. The root of it is this: Rāvaṇa had every comfort, joy, pleasure and power he could want. There was no one to stand against his might. He was a great devotee. In Rāvaṇa, who had such great qualities, kāma … took control. So, though he had so much wealth, though he had the strength of numbers, of money, of intellect and of body, every kind of power, he brought ruin on his own whole line, through kāma.
In the Bhāgavatam there is Hiraṇyakaśipu. He tried to make all the worlds believe in him as God, saying that there was no God other than he. Saying that there was no Nārāyaṇa greater than himself, he turned into a hater of Nārāyaṇa. He made inquiries of many kinds. He was a hater of Hari. But what became of him in the very end? To hate Hari: this, precisely, is krodha. Krodha is Hiraṇyakaśipu himself.
Then, in the Mahābhārata, there is Duryodhana. He longed to enjoy and delight in everyone's property all by himself. Sacrifice is nowhere to be found in him, in any corner. He was a greedy man. What became of this greedy Duryodhana in the end? He brought everything to ruin.
In the Rāmāyaṇa, Rāvaṇa is kāma. In the Bhāgavatam, Hiraṇyakaśipu is krodha. In the Mahābhārata, Duryodhana is the greedy man. In each story … there was kāma, krodha or lobha. But in this Kali age, kāma, krodha and lobha are crammed full in every single man. What use is it for such men to read the Rāmāyaṇa, what use to read the Bhāgavatam? What use to read the Mahābhārata? We must root out kāma, krodha and lobha. This alone is the Dharma of man in this Kali age. … who holds to such Dharma, the world has never overcome.
No one, whoever he be, can overcome you if you never swerve from Dharma: this is the great blessing of the Bhārata, is it not!
