'Abdu'l-Bahá
One Paragraph

Similarly in the world of being there exist forces unseen of the eye, such as the force of ether previously mentioned, that cannot be sensed, that cannot be seen. However, from the effects it produceth, that is from its waves and vibrations, light, heat, electricity appear and are made evident. In like manner is the power of growth, of feeling, of understanding, of thought, of memory, of imagination and of discernment; all these inner faculties are unseen of the eye and cannot be sensed, yet all are evident by the effects they produce. (2:22)
