October 18

The power of the Holy Spirit, enlightening man’s intelligence, has enabled him to discover means of bending many natural laws to his will. He flies through the air, floats on the sea, and even moves under the waters.

All this proves how man’s intelligence has been enabled to free him from the limitations of nature, and to solve many of her mysteries. Man, to a certain extent, has broken the chains of matter.

The Holy Spirit will give to man greater powers than these, if only he will strive after the things of the spirit and endeavour to attune his heart to the Divine infinite love. 
(‘Abdu’l-Baha, from a talk, Paris, October 24, 1911, ‘Paris Talks’)
