This perfected body can be compared to a mirror, and the human spirit to the sun. Nevertheless, if the mirror breaks, the bounty of the sun continues; and if the mirror is destroyed or ceases to exist, no harm will happen to the bounty of the sun, which is everlasting. This spirit has the power of discovery; it encompasses all things.
Abdu'l-BaháAn humble man without learning, but filled with the Holy Spirit, is more powerful than the most nobly-born profound scholar without that inspiration. He who is educated by the Divine Spirit can, in his time, lead others to receive the same Spirit.
Abdu'l-BaháIn every aspect of life, purity and holiness, cleanliness and refinement, exalt the human condition . . . Even in the physical realm, cleanliness will conduce to spirituality.
Abdu'l-Bahá
