All things are involved in all things[edit]
"Inasmuch as the fundamental principle of the teaching of Bahá'u'lláh is the oneness of the world of humanity, I will speak to you upon the intrinsic oneness of all phenomena. This is one of the abstruse subjects of divine philosophy.
"Fundamentally all existing things pass through the same degrees and phases of development, and any given phenomenon embodies all others. An ancient statement of the Arabian philosophers declares that all things are involved in all things."
Supplicate God to confirm us not to cut His green and verdant trees[edit]
"We must supplicate God that He may confirm and assist us...not to cut His green and verdant trees; not to prevent the descent of heavenly blessings, but to become confirmed in such wise as to adorn the realm of humanity, to illumine the East and the West, to create means of the interdependence of man, to destroy the basis of war and to become the cause of the affiliation of the hearts."
