Truth has many aspects ...

...When you meet those whose opinions differ from your own, do not turn away your face from them. Truth has many aspects, but it remains always and forever one.
Do not allow difference of opinion, or diversity of thought to separate you from your fellow-men, or to be the cause of dispute, hatred and strife in your hearts. Rather, search diligently for the truth and make all men your friends.
 Every edifice is made of many different stones, yet each depends on the other to such an extent that if one were displaced the whole building would suffer; if one is faulty the structure is imperfect.
Bahá’u’lláh has drawn the circle of unity, He has made a design for the uniting of all the peoples, and for the gathering of them all under the shelter of the tent of universal unity. This is the work of the Divine Bounty, and we must all strive with heart and soul until we have the reality of unity in our midst, and as we work, so will strength be given unto us.
