Man, restless and dissatisfied, runs from morn till eve, sailing the seas, diving beneath them in submarines, flying aloft in airplanes, delving into the lowest strata of the earth to obtain his livelihood -- all with the greatest difficulty, anxiety and unrest.

‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 184-185

The poor man at the gate of his palace spoke out, saying: "O kind king! Assuming that you are from every point of view so happy, free from every worry and sadness -- do you not worry for us? You say that on your own account you have no worries -- but do you never worry about the poor in your land? Is it becoming or meet that you should be so well off and we in such dire want and need? In view of our needs and troubles how can you rest in your palace, how can you even say that you are free from worries and sorrows? As a ruler you must not be so egoistic as to think of yourself alone but you must think of those who are your subjects. When we are comfortable then you will be comfortable; when we are in misery how can you, as a king, be in happiness?" The purport is this that we are all inhabiting one globe of earth. In reality we are one family and each one of us is a member of this family. We must all be in the greatest happiness and comfort, under a just rule and regulation which is according to the good pleasure of God, thus causing us to be happy, for this life is fleeting.

‘Abdu’l-Bahá, Foundations of World Unity, p. 41

We have toiled to build a community at a period when the world has witnessed startling changes which have profoundly altered the character of society and plunged it into an unprecedented state of worry and confusion. Indeed, the world in its current condition has lost its bearings through the operation of forces it neither understands nor can control.
