I remember not long ago my son-in-law, Itzchak telling me:
Tefillin are our antennas to Hashem!
And like an antenna, we are able to pray and have our signal amplified to G-d as well as be able to be imbued with G-d’s spirit and direction to us in life. With the Straps of the Tefillin as well as the boxes and knots, we spell out the letters of G-d’s name on our head and on our arm. Thus, we are not only wrapped in this “spiritual antenna,” but we literally wear G-d’s words on the parchment in the Tefillin boxes and with His holy name stamped on our centers of thought and feeling.
In short, Tefillin is opportunity for us to network over Wi-Fi with the Master of the Universe. It takes us out of the daily grind of looking at the world in selfish, shortsightedness of what’s in it for me today, and how can I get more gold and goodies than the next guy or girl. Inside all of us, we have a soul from G-d, and through our spiritual Wi-Fi connection, we can energize that part of ourselves with a good, strong signal straight to the Big Guy upstairs.
