Vak or hukam may be read individually by the seeker from die Holy Book in the gurdwara or in his own home or he may request the granthi (officiant) or any one else present to read it out for him. The Sikh Rahit Maryada or the code governing Sikh belief and practice published by the Shiromani Gurdwara Parbandhak Committee, statutorily elected religious body representative of the entire Sikh community, lays down the following procedure under the head hukam laina : (a) To bow before the Guru Granth Sahib. respectfully to attend the sangat which truly represents die Guru, and to recite or listen to vak amounts to having the darshan or sight of the True Guru. To have a sight of the Guru Granth Sahib by uncovering it and then not to read the vak is manmator self willed transgression.
(b) During the congregation, only one diing should take place at a time kirtan, discourse or scripture reading. (c) During the congregation, only a Sikh (man or woman) is entitled to sit in attendance of the Guru Granth Sahib. (d) While any one, Sikh or non Sikh, may read the Scripture for himself, only a Sikh should read it aloud for the sangat. (e) For obtaining vak, the hymn at the top of die left hand page of Guru Granth Sahib opened at random should be read out from the beginning. If the beginning is at the preceding page, the leaf may be turned.
A complete hymn should be read ending with the line where usually the name Nanak appears. (f) Hukam should also be picked from the holy book at the end to mark the close of the ceremony.Vak thus recited in slow rhythm and with correct intonation makes .impact on the listeners.It is taken to be the Guru`s command for the day.
Historically, there have been instances when theological or even mundane disputes have been settled by having recourse to vak. For example, on 12 October 1920, when the priests of the Harimandar refused to accept the sacrament (karah prasad) brought by a group of the so called low castes, it was agreed to obtain the Guru`s verdict The priests agreed. As the custom goes, the Guru Granth Sahib was opened at random and the words read impromptu went unambiguously in favour of the reformers. This was accepted without argument and without question. Such reliance on vak arises from the belief of the devotees that the barn of Guru Granth Sahib is revelation enjoying Divine sanction.
