"The Divine Reality may be likened to the sun and the Holy Spirit to the rays of the sun. As the rays of the sun bring the light and warmth of the sun to the earth, giving life to all created beings, so do the ’Manifestations’ bring the power of the Holy Spirit from the Divine Sun of Reality to give light and life to the souls of men". - 'Abdu'l-Bahá, Paris Talks, p. 57.
"So powerful is the light of unity that it can illuminate the whole earth".
- Bahá'u'lláh
