The 10 Sikh Gurus

The foundation of Sikhism was laid down by Guru Nanak Dev Ji. Guru Nanak Dev Ji infused his own consciousness into a disciple, who then became Guru, subsequently passing the light on to the next, and so on. The word "Guru" is derived from the root words "Gu", which means darkness or ignorance, and "Ru", which means light or knowledge The Guru is the experience of Truth (God).
Each one of the ten Gurus represents a divine attribute:

Guru Nanak - Humility
Guru Angad - Obedience
Guru Amar Das — Equality
Guru Ram Das - Service
Guru Arjan - Self-Sacrifice
Guru Hargobind - Justice
Guru Har Rai - Mercy
Guru Harkrishan - Purity
Guru Tegh Bahadur - Tranquility
Guru Gobind Singh - Royal Courage

Guru Gobind Singh, the Tenth Guru, exemplified the Sikh ideal of the Soldier-Saint. He was also an inspired and prolific writer, courageous warrior, and a source of Divine Wisdom to his Sikhs. "When all other means have failed," he said, "only then is it righteous to take up the sword." He was the defender of the poor, the meek, and the oppressed masses of India.
