The duty of kindness and sympathy towards strangers and foreigners...

When a man turns his face to God he finds sunshine everywhere. All men are his brothers. Let not conventionality cause you to seem cold and unsympathetic when you meet strange people from other countries. Do not look at them as though you suspected them of being evil-doers, thieves and boors. You think it necessary to be very careful, not to expose yourselves to the risk of making acquaintance with such, possibly, undesirable people.

I ask you not to think only of yourselves. Be kind to the strangers, whether come they from Turkey, Japan, Persia, Russia, China or any other country in the world.

Help to make them feel at home; find out where they are staying, ask if you may render them any service; try to make their lives a little happier.

In this way, even if, sometimes, what you at first suspected should be true, still go out of your way to be kind to them - this kindness will help them to become better. After all, why should any foreign people be treated as strangers?

Let those who meet you know, without your proclaiming the fact, that you are indeed a Baha'i. Put into practice the Teaching of Baha'u'llah, that of kindness to all nations. Do not be content with showing friendship in words alone, let your heart burn with loving kindness for all who may cross your path.
Abdu'l-Baha, Paris Talks, 1911
