Guru Angad dev ji had already tested Sri Amardas ji many times and on each occasion he came out victorious. Every time he displayed all the vitues required to make him the next Guru.
the last and Final trial came on a dar and rainy night. A Couple of hours before dawn, the Guru Ji demanded some water. None of his sons heard him. He called a second time which again fell on deaf fears, but this time Sri Amardas ji heard the voice and Immediately came to guruji and said most humbly , “Great Master, thy slave will fetch the water”. The Guru Said,” You have grown too old to run such errands for me. (In actual this all play was of Guruji , He wanted to take test of his dear sikh)” But then , Sri Amardas ji replied ” On the contrary, I have grown young on hearing my Guru’s order”.
And then without wasting a moment, he placed a pitcher on his head and rushed towards the nearby river. He filled his pitcher, began to repeat the Japji and Hastened back in the direction of the Guru’s house. With the Pitcher of water balanced delivately on his head, He waded through knee deep water. Because of the rain and storm, he lost his way. While groping through the dark, he happened to go past a weaver’s house. there his foot hit against a peg and he fell into the hole of the weavers loom. Yet he held fast on to the Pitcher.
On Hearing the Crashing sound outside their house, the weaver woke up to see who it was. His wife was quick to recognize Sri Amardas ji. She muttered to her husband, “None other than Amru could have stirred out on some vague errand for his Guru on a dark and stormy night like this.” She went on to curse his Guru for exploiting him.
Sri Amardas ji could not stand a word agains his Guru, He said sharply to the Weaver’s wife, ” You have gone out your mind or wouldn’t say such things about my guru” Saying thus he went away with the Pitcher of water for the Guru’s bath.
It is believed that after this incident , the weaver’s wife actually went insane until such time that her husband sought forgiveness of Guru Angad dev ji. Guru Angad deve ji Nominated Sri Amardas as his successor. He bathed him, dressed him in new clothes and seated him on the Guru’s gaddi order Bhai Budda Ji, a senior sikh, to apply ’tilak’ on his forehead.
Then the Guru bowed before Guru Amardas ji and Said before everyone press ,”sri Amardas ji is Guru Amardas ji now and He will be the Guru after me”.
