Ye are My treasury, for in you I have treasured the pearls of My mysteries and the gems of My knowledge. — Bahá’u’lláh
O Ye Sons of Spirit! Ye are My treasury, for in you I have treasured the pearls of My mysteries and the gems of My knowledge. Guard them from the strangers amidst My servants and from the ungodly amongst My people.
