Tirukkural 411: Heaing Knowledge

Wealth (gained) by the ear is wealth of wealth; that wealth is the chief of all wealth.

Image of Satguru Sivaya Subramuniyaswami
When the intellect is prominent, arrogance and analytical thinking preside. When the superconscious soul comes forth the refined qualities are born--compassion, insight, modesty and the others.
—Gurudeva
