The first time that baba nand singh did darshan of satguru nanak from Sri guru granth sahib jee, Baba Jawand singh jee ( rajajansee wale) were also present with baba jee. They both made a promise that until Satguru Nanak Dev Jee Does not give darshan by becoming pargat from Sri Guru Granth Sahib Jee and eat the parshaada they had prepared for them, they would not eat anything.
In this manner , for 6 long days they did not eat anything, but prepared parshaada for satguru everyday by doing continuous ardaas at the lotus charan of satguru jee. In such situation , they were on the verge of death , but both mahapursh did not give up , remembering Bhagat Ravidaas Jee's Bachan ' Ehu Janam Tumaare Lekhe.'
Finally Parkash came from Satguru granth sahib and Sri guru nanak dev jee Gave their darshan to both mahapursh. Baba jee offered satguru jee their parshaada and guru sahib ate their food with much happiness and blessed both mahapursh. 1st guru sahib said to baba jawand singh jee, ask for anything you want. Baba jawand singh ji replied 'whenever i do keertan, please bless me with your partakh darshan satguru jee!' Guru sahib Said ok, you will definatley get my darshan , but even those who even listen to your keertan , even they will get darshan.
Now as we can see baba jawand singh jee had asked, but now it was Baba Nand Singh Jee's turn. Guru sahib asked them, what do you want? Very humbly, baba ji replied, " sache paatshah ! i don't even know how to ask from you " ( daas nu mangna nahee aunda!") Just do one thing, and make me yours! I dont need anything else.' These were the bachans of baba ji proving their absolute piar,prem,bhaavna for guru sahib.
When Dhan guru nanak dev jee walked up to baba nand singh jee and hugged them and said-
'je tu mera hoe, taa sabh jag tera hoe'
If you are mine, then the whole world will be yours...
