In case you don’t understand some of the lingo used on this site:
A guru is one who is enlightened. “Gu” means ignorance, and “ru” means enlightenment. So it’s someone who has gone from ignorance to enlightenment, and has become a “teacher.” Sikhs had 10 living Gurus, or “prophets” from 1469-1708. The current Guru is our sacred text, the Sri Guru Granth Sahib.
Gurbani is the “Word of the Guru.” The entire contents of the Sri Guru Granth Sahib is “Gurbani”.
The word Sikh means “student.” A more precise translation is “a seeker of the Truth.”
Sikhi is how Sikhs refer to Sikhism. Or, Sikhism is how English-speakers refer to Sikhi.
A way of life started in the late 1400s that stresses 100% equality of all people, earning an honest living, sharing that earning with others, and meditation on the Infinite. With about 22 million followers worldwide, Sikhism checks in as the world’s 5th largest faith group in the world almanac.
