over 10 (with the exception of 12) is considered moving. Calendric cycles and astrology There is a tradition of Taoist thought which explores numerology, esoteric cosmology, astrology and feng shui in connection with the I Ching. The eleventh-century Neo-Confucian philosopher Shao Yung contributed advanced methods of divination including the Plum Blossom Yi Numerology, a horary astrology that takes into account the number of calligraphic brush strokes of one's query. Following the associations Carl Jung drew between astrology and I Ching with the introduction of his theory of synchronicity, the authors of modern Yi studies are much informed by the astrological paradigm. Chu and Sherrill provide five astrological systems in An Anthology of I Ching and in The Astrology of I Ching develop a form of symbolic astrology that uses the eight trigrams in connection with the time of one's birth to generate an oracle from which further hexagrams and a daily line judgement are derived. Another modern development incorporates the planetary positions of one's natal horoscope against the backdrop of Shao Yung's circular Fu Xi arrangement and the Western zodiac to provide multiple hexagrams corresponding to each of the planets. Wen Wang Gua method This method goes back to Jing Fang (78–37 BC). While a hexagram is derived with one of the common methods like coin or yarrow stalks, here the divination is not interpreted on the basis of the classic I Ching text. Instead, this system connects each of the six hexagram lines to one of the Twelve Earthly Branches, and then the picture can be analyzed with the use of 5 Elements (Wu Xing). By bringing in the Chinese calendar, this method not only tries to determine what will happen, but also when it will happen. As such, Wen Wang Gua makes a bridge between I Ching and the Four Pillars of Destiny. Software methods The preceding ("concrete"/physical) methods can be simulated in ("abstract"/conceptual) software. This has the theoretical advantage of improving randomness aspects of consulting the I Ching ("not-doing" in the personal sense, enhancing the "universal" principle). For all methods, one must pre-focus/prepare the mind. Here is a typical example for the "modified three-coin" method: #!/usr/bin/env python3 # # iChing_Modified_3_coins.py # # see https://github.com/kwccoin/I-Ching-Modified-3-Coin-Method # # Create (two) I Ching hexagrams: present > future (might be same). # # With both "3-coin method" and "modified 3-coin method" (see <nowiki>https://en.wikipedia.org/wiki/I_Ching_divination</nowiki>). # # 3-coins Probabilities: # old/changing/moving yin "6
