The evidences of discord and malice are apparent everywhere, though all were made for harmony and union.
The Great Being saith: O well-beloved ones! The tabernacle of unity hath been raised; regard ye not one another as strangers. Ye are the fruits of one tree, and the leaves of one branch.
We cherish the hope that the light of justice may shine upon the world and sanctify it from tyranny.
If the rulers and kings of the earth, the symbols of the power of God, exalted be His glory, arise and resolve to dedicate themselves to whatever will promote the highest interests of the whole of humanity, the reign of justice will assuredly be established amongst the children of men, and the effulgence of its light will envelop the whole earth.
~ Bahá’u’lláh, Tablets of Bahá’u’lláh
If we look reflectively upon the material world, we realize that all outer phenomena are dependent upon the sun. Without the sun the phenomenal world would be in a state of utter darkness and devoid of life. All earthly creation — whether mineral, vegetable, animal or human — is dependent upon the heat, light and splendor of the great central solar body for training and development. Were it not for the solar heat and sunlight, no minerals would have been formed, no vegetable, animal and human organisms would or could have become existent. It is clearly evident, therefore, that the sun is the source of life to all earthly and outer phenomena.
In the inner world, the world of the Kingdom, the Sun of Reality is the Trainer and Educator of minds, souls and spirits. Were it not for the effulgent rays of the Sun of Reality, they would be deprived of growth and development; nay, rather, they would be nonexistent. For just as the physical sun is the trainer of all outer and phenomenal forms of being through the radiation of its light and heat, so the radiation of the light and heat of the Sun of Reality gives growth, education and evolution to minds, souls and spirits toward the station of perfection.
~ Abdu’l-Bahá, The Promulgation of Universal Peace
