In plain words
You can easily understand the difference between a vānara and a mānava. Vā-nara. The difference between vānara and nara. Va means vālamu, a tail. One joined to a tail is a vānara. One without a tail is a nara. But the antics of both are one and the same. In the vānara there is nothing of the nara, but in the nara there is the vānara in abundance. Today we must enter on such a sacred path precisely to put away that remainder. Only through such inquiry did Śaṅkara's disciples proclaim well to the world the principles of morality and honesty. Without morality and discipline, no one in authority, however sacred, can be rid of Ajñāna. We must keep these rules of morality well. We must not fall prey to causeless excitements or to excitements that make no sense. Even the evil tendencies called kāma, krodha and dveṣa we must try, at this young age, to curb well. That is why Vēmana packed a fine meaning into little verses.
He who has eaten the dog is guru, jaṅgama and liṅga; he who has eaten the pig is the supreme yogi; he who has eaten the elephant, how great a sujñāni he is! Viśvadābhirāma, listen, O Vēma.
Why did the dog get that name? Vēmana gave the name dog to anger. When one has crushed anger down, has killed it, he is truly the very form of the liṅga, he said. He who has eaten the pig is the supreme yogi. To the pig he gave the name Ahaṅkāra. The elephant means pride, arrogance. These three, anger, Ahaṅkāra and pride: whoever among us has digested them and crushed them down is a great yogi, Vēmana declared. So, you who are young today: giving no place to Ahaṅkāra or to arrogance, we must try to carry life ever forward with a most noble heart, with sacred feeling, with cittas of Prema, Satya and forbearance. You must understand that by doing so humanness becomes true to its name. Hoping that, purifying your cittas with such sacred teachings, little by little, when these summer classes are over and you return to your own places, you too will make such sacred feelings your friends, bring all such things to your companions, form small committees and through this develop the culture of our Bhārata, and blessing you, I bring My talk to a close.
