Tirukkural 847: Being Ignorant

The fool who neglects precious counsel does, of his own accord, a great injury to himself.

Image of Satguru Sivaya Subramuniyaswami
A satguru is needed because the mind is so cunning and the ego is a self-perpetuating mechanism. It is he who inspires, assists, guides and impels the shishya toward the Self of himself.
—Gurudeva
