The Sikh scriptures are unique among the religious "Holy Books" of the world in that they don't just offer spiritual guidance for the Sikhs alone but impart guidance and assistance for all the peoples and religions of the world.
The Siri Guru Granth is a supreme treasure for all mankind. It is the true and permanent spiritual guide of the Sikhs. Guru Granth Sahib transcends creed and caste, cant and convention. It does not belong to the Sikhs alone. It consecrates the sayings of 11 Hindu bhagats and as many bard poets and seven Muslim saints, along with the teachings of six Sikh gurus.
