First Parkash

First Parkash (opening ceremony) of the Sri Guru Granth Sahib, the main Sikh scripture, is observed on September 1. The Granth, or Adi Granth, is a collection of prayers and hymns. The fifth Sikh guru, Arjan Dev Ji, compiled words and verses from all the Sikh Gurus and other saints to create the Granth.

When Guru Arjan finished compiling the Granth’s 1,430 pages and 5,864 verses, he placed it in the new Harmandir Sahib in Amritsar. He performed the first parkash there on 1 Bhadon Sudi, Samvat 1661 (August 30, 1604). The Adi Granth was a turning point for the Sikh faith, marking its separation from Hinduism and Islam.
