**Rudhyar: Formula of Change**

We referred to the ** Yi King** of ancient China and to its “

**Formula of Change**” based on the interplay of the two cosmic polarities

**and**

*Yang***. As already mentioned, such a formula is of special interest to us because it had obvious astrological origins. Moreover it is a characteristic expression of a philosophy of time, such as we postulated in a previous chapter as the necessary background for any consistent and valid astrological thought. Astrology is philosophically meaningless unless it rests on a thorough understanding of cycles and of the creative potency of every moment — especially those “seed-moments” which become such by reason of their being the points of departure of cycles. The “Formula of Change” of the**

*Yin***is a cyclic formula, which purports to determine symbolically the universal and essential structure of all cycles; better still, of**

*Yi King***Cycle or of**

*the***. As all life-processes are cyclic — in essence, if not in outer appearance — such a formula becomes the basic law of all life-processes. Thus a truly universal synthesis of being and becoming is reached — a synthesis probably grander and more absolute, in its symbolical applicability, than that contemplated by Einstein through his “unified field theory” reducing all natural phenomena to a simple law.**
