Their names are reverently preserved in Sikh memory and are recalled every time Sikh ardas or prayer of supplication is recited at a congregation or privately by an individual. See AJIT SINGH.

VAK, from Sanskrit vaka (sounding, speaking ; a text, recitation or formula) or vakya (speech, saying, statement, declaration, a sentence or period), has a special connotation in the Sikh system. In Sikh terminology, Vak means the command or lesson read from the Guru Granth Sahib. Vak laina or hukam laina (obtaining or receiving the Guru`s word or command) is for the Sikhs tantamount to having a darshan or audience of the Guru Granth Sahib, ever present Guru for them. It is an act of seeking the counsel or instruction of the Guru who `speaks` through the vak or hymn recited aloud. Customarily, vak or hukam is recited in sangat by an officiant after the installation or opening of the Guru Granth Sahib in the morning and every time after ardas or supplicatory prayer is said at die end of the service.
