"The basic foundation principle is one God for all people and everyone is considered equal in the eyes of God -- which means gender, race and ethnicity," said Kaur.
Sikhs say one can get closer to God by practicing three things: remembering God, living truthfully and offering service to humanity. They say they are meant to uphold the values of honesty, compassion, generosity, humility, integrity and spirituality on a daily basis.
The five articles of faith include the unshorn hair [kes], comb for good hygiene [khangha], steel bracelet [kara], sword [kirpan] and soldier's shorts [kachhehra].
