Unity

Bahá’u’lláh wrote:

“He is a true believer in Divine unity who, far from confusing duality with oneness, refuseth to allow any notion of multiplicity to becloud his conception of the singleness of God, who will regard the Divine Being as One Who, by His very nature, transcendeth the limitations of numbers.”
(Gleanings from the Writings of Bahá’u’lláh, p. 166-167)

“…Know thou assuredly that the essence of all the Prophets of God is one and the same.  Their unity is absolute.…”
(Gleanings from the Writings of Bahá’u’lláh, p. 78)

“O contending peoples and kindreds of the earth! Set your faces towards unity, and let the radiance of its light shine upon you…There can be no doubt whatever that the peoples of the world, of whatever race or religion, derive their inspiration from one heavenly Source, and are the subjects of one God. The difference between the ordinances under which they abide should be attributed to the varying requirements and exigencies of the age in which they were revealed…”
(Gleanings from the Writings of Bahá’u’lláh, p. 217)

“…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…”
(Gleanings from the Writings of Bahá’u’lláh, p. 218)

‘Abdu’l-Bahá said:

“As difference in degree of capacity exists among human souls, as difference in capability is found, therefore, individualities will differ one from another. But in reality this is a reason for unity and not for discord and enmity. If the flowers of a garden were all of one color, the effect would be monotonous to the eye; but if the colors are variegated, it is most pleasing and wonderful. The difference in adornment of color and capacity of reflection among the flowers gives the garden its beauty and charm. Therefore, although we are of different individualities, different in ideas and of various fragrances, let us strive like flowers of the same divine garden to live together in harmony. Even though each soul has its own individual perfume and color, all are reflecting the same light, all contributing fragrance to the same breeze which blows through the garden, all continuing to grow in complete harmony and accord.  Become as waves of one sea, trees of one forest, growing in the utmost love, agreement and unity.”
