Damdama Sahib earned a nickname usually reserved for one of Hinduism's great centres of learning, awarded to it specifically for scholarship rather than for any temple architecture.
Called the Varanasi of the Guru
The site is traditionally known as Guru Ki Kashi, meaning the Varanasi, or Kashi, of the Guru, a title reflecting its historical reputation as a centre for teaching Gurmukhi script and Sikh scripture, where scholars and scribes trained under the Guru's direction rather than the site being primarily known for pilgrimage architecture or relics.
A rest after battle
Guru Gobind Singh is understood to have stayed at the site following the Battle of Muktsar, using the period to rest his forces and, according to tradition, to undertake or oversee scholarly and scriptural work, connecting the site's martial and intellectual associations within the same short historical episode.
As this entry's companion article covers
The production of the definitive Damdami Bir recension of the scripture, dictated from memory after an earlier copy was lost, along with the historical dispute over whether Damdama Sahib properly counts as a fifth Takht alongside the four more traditionally recognised seats, are addressed in this entry's companion article rather than repeated here.
