Just as a pregnant woman takes all possible care of herself during her pregnancy and on completion of the period gives birth to a baby boy;
Then she observes and controls her eating habits meticulously and rigidly that helps the young child to grow healthy by consuming his mother's milk.
The mother cares not about all the filth of the child and brings him up to give him a healthy body.
So is a disciple (Sikh), like a child in this world who like the mother is blessed by the Guru with Naam Simran that ultimately emancipates him. (353)
