When these substances of abundant suction and abundant pressure meet, their movement is guided by the Law of Penetrability. All movement of matter is caused by a difference in Density whereby one substance penetrates another substance by the Push of Pressure and the Pull of Suction. Physical forces apply equally to living matter such as humans having sex, and to non-living matter such as rocks shooting through space. You might think Lawson is a tad mechanical in his view of life, but in fact the opposite is true. All substances, even those we view as non-living, Lawson believes to be imbued with Life.
Life is everywhere and in everything.
Only the short-sighted believe that matter moves in regular mathematical patterns, such as a circles and lines. To understand this, consider your own movement on earth. Even if you are walking in a straight line, the earth itself is rotating about its axis and revolving around the sun, which in turn is revolving around the galaxy, which is in turn moving about the universe. So your true movement in space is nothing like a straight line. It is more like a Zig, a Zag, and then a Swirl.
