Tirukkural 242: Compassion

(Stand) in the good path, consider, and be kind. Even considering according to the conflicting tenets of the different sects, kindness will be your best aid, (in the acquisition of heavenly bliss).

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
