Tirukkural 547: The Right Sceptre

The king defends the whole world; and justice, when administered without defect, defends the king.

When guests come, they must be given hospitality, at least a mat to sit on and a glass of water to drink. These are obligatory gifts. You must never leave your guest standing, and you must never leave your guest thirsty.
