Bahá’í Sacred Writings, Bahá’u’lláh, #10

These Prophets and chosen Ones of God are the recipients and revealers of all the unchangeable attributes and names of God. They are the mirrors that truly and faithfully reflect the light of God. Whatsoever is applicable to them is in reality applicable to God, Himself, Who is both the Visible and the Invisible. The knowledge of Him, Who is the Origin of all things, and attainment unto Him, are impossible save through knowledge of, and attainment unto, these luminous Beings who proceed from the Sun of Truth. By attaining, therefore, to the presence of these holy Luminaries, the “Presence of God” Himself is attained.
