Shabd is inexhaustible
The Shabd has no end. Its supply is inexhaustible.
He to whom He is kind lacks nothing. Oh Nanak, Shabd is inexhaustible, however much one may spend.
Shalok M5, 1426-2
The Guru's Shabd is limitless. It has no end. It is beyond the reach of Kal.
You are the Friend, the Wise, the One who unites. Through the Guru's Word I praise You. But there is no end to Your praise. Kal cannot reach where the Lord's Name abides.
Sri Rag M1, 55-16
