In plain words
One may learn every branch of learning and win over the assembly; men may become heroes and fight on the battlefield; one may be born a king of kings and rule a kingdom; one may make gifts of gold and of cows; one may count the stars of the sky; one may recite the names of living creatures; one may learn all the eight-limbed sciences; one may make the journey to the moon; but, restraining the body, the senses and the rest, steadying the mind and turning it inward, becoming Ātmas, unceasingly still, men cannot stand firm in steady discipline.
Man has found the way to go to the moon, but he does not learn even half an inch of the way to go to his inner Ātma. Only he who recognises the principle of Satya within him is truly educated. Rāvaṇa too studied what Rāma studied. But what did Vālmīki, who composed the Rāmāyaṇa, say? He said that Rāvaṇa was an utter fool and Rāma a great man of Jñāna. Why? Rāma put his learning into practice, set an ideal before others and toiled for the welfare of the world. But Rāvaṇa did not put his learning into practice; becoming a slave to the senses, he burnt himself and all he had to ashes. The studies we pursue are not for the sake of enjoying the pleasures of the senses. We must offer the world, as an ideal, the principle of character that lies beyond the senses. But the students of today misuse their studies with impure feelings.
All good deeds, true and eternal, are taking on a deformed shape; a sacred nature is leaving the people day after day; the practice of Dharma and compassion is ever taking on a deformed shape; the noble learning of the Vedas is laid low, and evil learning keeps growing.
