“A man had two sons. The father sent them to a preceptor to learn the Knowledge of Brahman. After a few years they returned from their preceptor’s house and bowed low before their father. Wanting to measure the depth of their knowledge of Brahman, he first questioned the older of the two boys. ‘My child,’ he said, ‘you have studied all the scriptures. Now tell me, what is the nature of Brahman?’ The boy began to explain Brahman by reciting various texts from the Vedas. The father did not say anything. Then he asked the younger son the same question. But the boy remained silent and stood with eyes cast down. No word escaped his lips. The father was pleased and said to him: ‘My child, you have understood a little of Brahman. What It is cannot be expressed in words.'
"Men often think they have understood Brahman fully. Once an ant went to a hill of sugar. One grain filled its stomach. Taking another grain in its mouth, it started homeward. On its way, it thought, ‘Next time I shall carry home the whole hill.’That is the way shallow minds think. They don’t know that Brahman is beyond one’s words and thought. However great a man may be, how much can he know of Brahman? Shukadeva and sages like him may have been big ants; but even they could carry at the utmost eight or ten grains of sugar!
