Before he became Guru, Amar Das walked far to the river every single morning, long before sunrise, to bring back fresh water for his teacher Guru Angad — for many, many years, without ever missing a day.
One stormy night he stumbled in the dark and fell, but he held the water pot safe and would not turn back, determined to serve.
His steady, humble devotion, kept up faithfully for so long, led Guru Angad to choose him as the next Guru, though he was already an old man.
