Daas mentioned before this story in a debate about what types of food we can eat. It's clear that many Sakhi's show how singhs used to prepare sweets for sangat. The following is a passage from the book "Episodes in the lives of the Guru's"
KEY TO HAPPINESS
Once Mata ji developed some physical ailment. When the Guru came for his meals, she
prayed, "O True Emperor, I have suffered much pain. Pray give me comfort and relief from
this suffering."
"O Mother, you want comfort and relief for yourself. Have you yourself ever given these to
anybody?" asked the Guru.
"In what way can I do that?" replied Mata ji.
"Have you ever served a meal to anybody? Have you ever offered cold water to anybody?
Have you ever fanned anybody? Have you ever massaged a tired person?"
"O True Emperor, because of you, there are so many people eager to serve food and
water, to wield the fan and to do the massaging, that many of them do not even get a turn
to perform these services. How can I do that?"
"Mata ji, he alone can get comfort or peace, who gives it to others. This is the Law laid
down by the Lord Himself. And if you have not given comfort to anybody, how can you
aspire for it yourself?"
"O True King, the past is past. In future I shall do as you say."
"Very well said," remarked the Guru, "now let us proceed like this. Let us hold a big feast,
cook wholesome, delicious food including luchis, jalebis, kichoris, and invite all the four
vamas. We should seek the pleasure and blessings of all."
Mata ji complied with the wishes of the Guru. A huge feast was organised. All the four
vamos were invited. Followers of all the six systems of philosophy were invited, and all
near and dear ones as well as those distantly connected, joined. All showered their
blessings. The feast continued for several days, with no restrictions. "Dear Mother, now
you have earned the pleasure of so many. Therefore, you will also have comfort ahd
peace," said the Guru. Thus ended Mata ji's ailment. (33)
