Karma is Action and, from the standpoint of the metaphysician as well as that of the student of Occultism and Esotericism, that Action is devoid of any personality. Karma gives birth to beings but its movement is sui generis, and it is above its creatures. Its intelligence is like that of a river—its waters find their own levels, make their own channels, and, however weary their journey, they wind surely to their destined sea. Its justice “knows not wrath nor pardon,” and is exhaustless in nature. Says The Secret Doctrine:“Karma is a mysterious law and no respecter of persons.”
Karma is the perpetual motion in the Absolute and its character is dual—cause and effect, Spirit-Matter, the primal pair in the manifestation of the One Life. There is no such thing as a causeless effect; there is no effect which does not become in its turn a cause; no Spirit without Matter and no Matter without Spirit. Thus we come to the third element of Karma—Fohat, the relation between Cause and Effect, Spirit and Matter. This is the totality of the beings which compose “Nature.”
