Raj Karega Khalsa

Raj Karega Khalsa (Punjabi: ਰਾਜ ਕਰੇਗਾ ਖਾਲਸਾ, romanized: Rāja karēgā khālasā, lit.'the pure will rule') is a slogan representing the Sikh idea of sovereignty and it is recited at the conclusion of Ardas. Originally, the phrase was part of a short couplet that later came to become part of the daily Sikh supplication prayer.

The complete quote is ' Raaj Karega Khalsa, Aaki Rahe Na Koye'. Aaki means corrupt or impure (opposite of Khalsa i.e. pure or pawitar).
