For instance,Guru Nanak has written astpadfs in ragas Gauri and Maru; those under measure Gauri are in Chaupai metre and those under Maru in Nishani metre. All the twenty-four astpadis which constitute Guru Arjan`s Sukhmani are in Chaupai metre and Gauri raga. Although each of the eight stanzas in an astpadfo Sukham" comprises ten verses, the number of verses in a stanza elsewhere in the Scripture is restricted from two to four lines.
