Tirukkural 298: Veracity

Purity of body is produced by water and purity of mind by truthfulness.

Image of Satguru Sivaya Subramuniyaswami
The intellect in its capacity to contain truth is a very limited tool, while faith is a very broad, accommodating and embracing faculty. The mystery of life and beyond life, of Siva, is really better understood through faith than through intellectual reasoning.
