Tirukkural 999: Courtesy

To those who cannot rejoice, the wide world is buried darkness even in (broad) day light

Image of Satguru Sivaya Subramuniyaswami
You must purify yourself. You purify yourself by being kind to others, being generous until it hurts, being benevolent, being ready to serve at all times until you are strained in serving. Put a smile on the faces of other people.
—Gurudeva
