NASIHAT NAMAH, lit. epistle of admonishment, is an apocryphal composition in verse attributed to Guru Nanak and is said to have been addressed by the Guru to king Croesus (Karun in Sikh chronicles). The King is advised to do good deeds when God has bestowed riches upon him. Money spent in a good cause is money well spent. Money belongs to him who spends it.

Everything in this world is transient and none should feel proud of his possessions which are bound to perish. True God alone shall abide forever. Karun could be a very rich man so named after the historical Croesus, king of Lydia, 5605-46 BC, known for his fabulous wealth.
