Sukhmani or Sukhmani Sahib is the title given to the Gurbani in raga Gauri Sukhmani in the Guru Granth Sahib which in turn appears in the major musical measure Raga Gauri to which it belongs. It is a lengthy composition, written by Guru Arjan Dev, the fifth Sikh Guru.
The sacred prayer spans 35 pages from page 262 to page 296 of the Guru Granth Sahib. Surprisingly, many ardent Sikhs include the recitation of this Bani in their daily regimen of Nitnem.
The physical site, where the Guru around AD 1602-03 composed this composition was once enclosed by a dense wood. The location is still marked on the bank of the Ramsar pool in the city of Amritsar, near the famous Golden Temple the Harimandir Sahib.
