Kabir's presence in the Sikh scripture is not an ecumenical gesture bolted on afterwards — he is structurally central, with 541 compositions distributed through the raags and a section of saloks of his own. He was a Muslim weaver in fifteenth-century Banaras who attacked Brahmin ritual and Islamic legalism with the same voice, and he died decades before Nanak began teaching. Guru Arjan included him without editing out the difficult material, and where a Guru disagreed with a bhagat's line the reply was printed alongside rather than the line removed, which is unusual behaviour for a scripture. Kabir is claimed simultaneously by the Kabir Panth, by Hindu bhakti traditions and by Sikhs, and each reads him differently. Sikh commentary treats him as bani — revealed word with the same authority as the Gurus' own — which is a stronger claim than most traditions make about an outsider.
