Kemadruma is unusual in being defined by what is not there. The Moon is unattended: no planet other than the Sun in the sign before it, none in the sign after, and in the stricter versions none with it. Where Sunapha, Anapha and Durudhara describe the Moon accompanied on one side, the other, or both, Kemadruma is the fourth case, the Moon alone.
That completeness is a clue to how these four were constructed. They are not four separate observations. They are an exhaustive partition of one variable, and every chart necessarily falls into exactly one of them. A scheme that carves the space up that way is a classification rather than a discovery, and its members inherit their meanings from the scheme's own logic: three kinds of support and one of isolation.
The tradition takes Kemadruma seriously and reads it as difficulty, isolation and want. It also supplies an unusually long list of cancellations, bhanga: a planet in an angle from the ascendant, a strong aspect to the Moon, the Moon in an angle, a well placed dispositor. The list is long enough that careful practitioners note the combination is far more often cancelled than allowed to stand.
The atlas records both the reading and the cancellations. Nothing here is a prediction and nothing here concerns any individual.
