"Sometimes one can demonstrate the most complex laws by means of the simplest apparatus. The law of Karma is complex, but take the Ruhmkorff coil or any other electric coil and you will get an evident image of karma. The current runs along the spiral uninterruptedly but the protective winding is subject to all outside reactions. In addition, each thread contacts the thread of the preceding round, carrying upon itself the consequences of the past. Thus, each hour changes one's karma, for each hour evokes the corresponding past. Thus, one may contact the entire line of past manifestations. But the same obvious example shows how the seed of the spirit is unharmed; and striving into the heights it sustains its shell without fearing the past. Verily, karma is threatening only to those who are plunged into inaction. But a striving thought is liberated from the burden of the past and, like a heavenly body, strives forward without retreading its path. Thus, even with a difficult karma, one may evince a useful liberation."
