Interpreting Yi-King correctly is not so difficult. This requires a little method.
To include/understand the two principal trigrams:
The lower trigram represents you, particularly line 2. It thus indicates the force which represents you in the situation
The higher trigram represents a sphere higher than you (country, company, family, etc.) It is thus necessary to be careful for indicating the level to which this trigram refers.
To include/understand the 2 interior trigrams the lower internal trigram (lines 2,3 and 4) represents your attitude and/or your feeling with respect to the higher force.
The higher internal trigram represents the attitude and/or the feeling of your superiors or the company with respect to you.
