In plain words
Kumbhakarṇa is the symbol of eating beyond all limit. He was always either eating or sleeping. Vibhīṣaṇa, though, remembered the name of Rāma without ceasing.
To counsel her husband for his good is the wife's duty
Rāvaṇa was not truly a demon. He performed many yajñas, yāgas and other rites. But because he gave in to lust, anger and other vices, the demonic entered him. His wife Mandodarī counselled him earnestly, again and again, to put those vices far from him.
When the husband turns wicked and is heading for harm, like a minister, humbly setting good and ill before him, to teach their husband his good, women ever should walk on this earth as Mandodarī did.
A wife is not merely one who gives physical pleasure. When the husband takes a wrong path, it is the wife's duty to counsel him for his good and lead him into the good path, into the principle of the Divine. Today they look on the wife as a servant-maid. That is a great mistake. The wife has come to teach her husband what is good for him. Sītā too gave Rāma a great deal of good counsel: “Lord! Only a certain few have sinned. So it is not good to kill all the demons. It is right to set straight those who did wrong,” she would say.
Only he who has virtue is a man
Women are very great; they have the right to teach men the proper path. Only through the encouragement of women, only through their divine powers, have men risen and protected the world. Who is a man? Only he who has virtue is a man. In the Rāmāyaṇa too, they held Rāma's virtue itself to be the chief thing. One is not a man merely because one has strength. One who has anger, delusion and other vices is not a man; we may call him nothing but a beast. In the world there are both good and bad. We must take in only the good and cast off the bad. Students, girls and boys especially, must set their qualities and their conduct on the proper path.
