Golden Temple: Harmandir Sahib literally means Temple of God. The fourth guru of Sikhism, Guru Ram Das, excavated a tank in 1577 CE which subsequently became known as Amritsar (meaning Pool of the Nectar of Immortality), giving its name to the city that grew around it. In due course, a splendid Sikh edifice, Harmandir Sahib (meaning the abode of God), rose in the middle of this tank and became the supreme centre of Sikhism. Its sanctum came to house the Adi Granth comprising compositions of Sikh gurus and other saints considered to have Sikh values and philosophies, e.g., Baba Farid, and Kabir. The compilation of the Adi Granth was started by the fifth guru of Sikhism, Guru Arjan Dev.
