In Rahitnama completed by Prehlad Singh, a conversation of Guru Gobind Singh Ji with Bhai Nand Lal is of utmost importance. It gives a gist of the duties a true Sikh should perform.
"O friend, hear me,
this is the way of life for a disicple of the Guru
Rise in the early hours of the morning, take bath,
recite Japji and Jap Sahib, and meditate on the
Name of the God in the evening, join the sangat
and hear the recitation of Rehras, the prasises of
God, and the edifying sermons. Those who follow
such a routine, always endure.
Nand Lal, listen carefully to what I say. In
these categories I sublist : the category of the
Attributes, the category of the Word of the Guru.
That which the Guru teaches, men should hear
and preach. Men should hear the word of the Guru
with love in their hearts and faith in their
minds. This, the Form of the Guru, the men should
behold, day in and day out. Men should serve
each other, without pride and selfishness.
Those who serve humanity, their service
do I acknowledge as the service to My person.
Listen, O Nand Lal, thus humanity shall be
freed and attain everlasting bliss."
