In the Guru Granth Sahib, after ‘Japu’ Ji Sahib, five Sabads are recorded on pages 8-10 under the title ‘So Daru.’ Regarding this, a note, ‘so daru panc sabad’ (So Daru comprising five Sabads) is written under the ‘index of rags’ (musical modes), in the manuscripts of the Guru Granth Sahib. From this information, it is clear that ‘So Daru’ is a collection of five Sabads. Out of these five, the first Sabad begins with the line ‘so daru terā kehā so gharu kehā....’ Thus, these five Sabads have received the title ‘so daru.’
