Origin Eighteenth century in its early form
The standing prayer, said before every undertaking and at the close of every Sikh ceremony, with the congregation on its feet and hands joined. It is the only major Sikh liturgical text that is not scripture, and it is the only one that is partly open.
Its structure is fixed in three movements. It opens with a stanza remembering the divine power and then naming the ten Gurus in order and the Guru Granth Sahib after them. It continues into a recital of the community's dead: those who kept faith under torture, who were cut apart limb by limb, scalped, broken on the wheel, sawn asunder; the women of the Mughal jails who watched their children killed and did not abandon their faith; those who fell defending gurdwaras. It asks that Sikhs be granted the gift of the Name, of faith, and of the sight of Amritsar. And it ends by asking for the good of all.
Then it opens. After the fixed portion, whoever is leading states the specific occasion, a birth, an illness, a journey, a business begun, an examination, a house moved into, in plain language, and the congregation answers. This is why the Ardas is said before almost anything, and why it does not sound like a formula when it is said. The fixed part supplies the memory and the frame; the variable part supplies the reason anyone is standing there.
It is the community remembering itself out loud, and it is said in this form daily by Sikhs who have no personal connection to any of the events it names. The recital of the martyrs is not history recited for information. It is the ground on which the petition that follows is made.
The Sikh Rehat Maryada sets out its wording, which was standardised in the twentieth century after considerable local variation. The opening line invoking bhagauti is understood in mainstream Sikh commentary as the divine power, and by some readers as the sword that stands for it; it is not read as the goddess Bhagavati.
