I am leaving Paris for the Orient though in reality I am always with you. Place does not matter. Two people may be in the same room and yet not attain to a visitation. When I was in prison many people came to see me. They crossed seas and deserts and yet remained in the city of the blind while others in far-distant lands attained the meeting.

‘Abdu’l-Bahá, Divine Philosophy, p. 187

It is obvious that all created things are connected one to another by a linkage complete and perfect, even, for example, as are the members of the human body. Note how all the members and component parts of the human body are connected one to another. In the same way, all the members of this endless universe are linked one to another. The foot and the step, for example, are connected to the ear and the eye; the eye must look ahead before the step is taken. The ear must hear before the eye will carefully observe. And whatever member of the human body is deficient, produceth a deficiency in the other members. The brain is connected with the heart and stomach, the lungs are connected with all the members. So is it with the other members of the body.
