(a) “The Causes of Existence” mean not only the physical causes known to Science, but the metaphysical causes, the chief of which is the desire to exist, an outcome of Nidâna and Mâyâ. This desire for a sentient life shows itself in everything, from an atom to a sun, and is a reflection of the Divine Thought propelled into objective existence, into a law that the Universe should exist. According to Esoteric teaching, the real cause of that supposed desire, and of all existence, remains for ever hidden, and its first emanations are the most complete abstractions mind can conceive. These abstractions must of necessity be postulated as the cause of the material Universe which presents itself to the senses and intellect, and must underlie the secondary and subordinate powers of Nature, which have been anthropomorphized and worshipped as “God” and “gods” by the common herd of every age. It is impossible to conceive anything without a cause; the attempt to do so makes the mind a blank. This is virtually the condition to which the mind must come at last when we try to trace back the chain of causes and effects, but both Science and Religion jump to this condition of blankness much more quickly than is necessary, for they ignore the metaphysical abstractions which are the only conceivable causes of physical concretions. These abstractions become more and more concrete as they approach our plane of existence, until finally they phenomenalize in the form of the material Universe, by a process of conversion of metaphysics into physics, analogous to that by which steam can be condensed into water, and water frozen into ice.
