In plain words
What does ‘Rāma’ mean? ‘Ramayatīti Rāmaḥ’: the principle of Rāma is that which gives delight.
‘Ē āv rā bā vā’
Once Śrī Kṛṣṇadevarāya put a question to the eight great poets of his court: could anyone join five syllables belonging to five different languages and make a sentence with meaning? He said that the five syllables must give the same meaning in each of those languages. He announced that whoever could answer his question by the next morning would be honoured grandly in the court. When the court had risen that day, Tenāli Rāmakṛṣṇa went for the night to the house of his brother-in-law in the same town. Since his brother-in-law had come, he arranged a cot and a mattress for him to sleep on that night. Rāmakṛṣṇa, “Brother-in-law! I must think hard tonight about the question the Mahārāja asked. If you spread a mattress for me, I will fall fast asleep. So have a cot put up for me in the cattle shed; that is enough”, he said. As he wished, a cot was put up in the cattle shed. Lying on that cot, Rāmakṛṣṇa was thinking long and deeply about the question the Mahārāja had asked. At one o'clock in the night a cow in that cattle shed was about to calve. Seeing it, Rāmakṛṣṇa got up: “Brother-in-law! The cow is calving. Come and see to her,” he called. From inside, he asked, “Which cow is it, bāvā?” For to his cows he had given Lakṣmī, Sarasvatī, Pārvatī …. as their names. On hearing these words, an idea flashed in Rāmakṛṣṇa's mind. He had found the answer to the Mahārāja's question. In a joy he could not contain, he too said, “Ē āv rā bā vā!” His brother-in-law asked again, “Which cow is it, bāvā?” Rāmakṛṣṇa answered, “Ē āv rā bā vā!” He thought that, for want of sleep that night, his brother-in-law must have lost his wits. Saying “Ē āv rā bā vā!” to himself again and again, Rāmakṛṣṇa rose at dawn, bathed and went to the royal court.
