A Western Approximation refers to an interpretive model that approaches the hexagrams from a Western perspective influenced by philosophical anthropology.
One of the core concepts of this approach is that we, as human beings, are bound in opposites, such as “relationship to ourselves / relationship to the world”, “individual / society” or “body / psyche”. These pairs of opposites shape our experience, we can never leave them, we are inescapably bound, just as in the interplay of Yin and Yang – which closes the arc to the origin of the I Ching.
The interpretive model is explained in more detail here: Follow the Path of the Dao: A Western Approximation
