The relation of guru and sewak is like that of Shabd(guru)sewak(Surat or soul)This relation is like that mother or the child.As the mother takes care of child,Guru takes care of His disciple.Initiation with nam to the disciple is like the disciple's second birth from guru.Guru takes care of him by all means as the mother takes takes of her child.Mother has limitations of her help but real guru gives his disciples all time help by creating love for Him in his heart.Guru is compared with koonj,which leaves it's young ones in Siberia comes to India and takes care of them by Simran and secondly with tortoise which gives it's youngones in the sand but it takes care from the water where it lives and takes care of it.Third is hen who takes care of its egg till the egg bursts and the young one is out of the egg. the guru takes care of his disciples.
