I Ching / Yijing

The Yijing or I Ching, the Book of Changes, is one of the oldest books in continuous use in the world. Its core is a set of sixty-four hexagrams — six-line figures built from broken (yin) and unbroken (yang) lines — each with a name, an image, and short judgement texts, later expanded by philosophical commentaries known as the Ten Wings.[1]

It began as a divination manual in early China and became a central classic of Confucian and Daoist thought, read as a description of how situations change. Consulting it traditionally involves casting yarrow stalks or coins to build a hexagram line by line; lines that are “changing” turn the figure into a second hexagram, describing a movement from one situation to another.

People explore the Yijing for its imagery and its counsel about timing and proportion — when to advance, when to wait, when to gather help. Reading it well is less about prediction than about holding a situation up to a very old set of images.

Traditional practice casts a hexagram in the moment of a question; it does not assign a hexagram at birth. Birth Mosaic therefore treats this as a reflective framework: we pair your profile themes with a hexagram for contemplation and say clearly that this pairing is our organisation, not an inherited birth calculation.

• What changing lines say about movement between situations
• Core ideas such as timing, balance, and proportion
• How the same text has been read as divination and as philosophy

Hexagram

A figure of six stacked lines; there are sixty-four in total.

Trigram

A three-line figure; two trigrams stacked make a hexagram.

Yin and yang lines

Broken and unbroken lines, the basic units of every figure.

Changing line

A line marked as in transition, turning one hexagram into another.

Ten Wings

Classical commentaries appended to the core text that shaped its philosophical reading.

Example: Hexagram 5, often translated as “Waiting,” uses the image of clouds gathering before rain and counsels patient preparation rather than forcing an outcome. Shown here to illustrate how a hexagram reads.

The Yijing is a classical Chinese text with millennia of commentary and many competing translations; wording differs considerably between them. Assigning a hexagram to a birth date is a modern convenience, not classical practice, and Birth Mosaic marks it as such.
