Among His teachings was the declaration of universal peace. People of different nations, religions and sects who followed Him came together to such an extent that remarkable gatherings were instituted consisting of the various nations and religions of the east. Every soul who entered these gatherings saw but one nation, one teaching, one pathway, one order, for the teachings of Bahá’u’lláh were not limited to the establishment of universal peace. They embraced many teachings which supplemented and supported that of universal peace. Among these teachings was the independent investigation of reality so that the world of humanity may be saved from the darkness of imitation and attain to the truth; may tear off and cast away this ragged and outgrown garment of a thousand years ago and may put on the robe woven in the utmost purity and holiness in the loom of reality. As reality is one and cannot admit of multiplicity, therefore different opinions must ultimately become fused into one. And among the teachings of Bahá’u’lláh is the oneness of the world of humanity; that all human beings are the sheep of God and He is the kind Shepherd. This Shepherd is kind to all the sheep, because He created them all, trained them, provided for them and protected them. There is no doubt that the Shepherd is kind to all the sheep and should there be among these sheep ignorant ones, they must be educated; if there be children, they must be trained until they reach maturity; if there be sick ones, they must be cured. There must be no hatred and enmity, for as by a kind physician these ignorant, sick ones should be treated. And among the teachings of Bahá’u’lláh is that religion must be the cause of fellowship and love. If it becomes the cause of estrangement then it is not needed, for religion is like a remedy; if it aggravates the disease then it becomes unnecessary. And among the teachings of Bahá’u’lláh is that religion must be in conformity with science and reason, so that it may influence the hearts of men. The foundation must be solid and must not consist of imitations.
