To interpret Yi-King well is not so difficult. That 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 trigram interns lower (lines 2,3 and 4) represents your attitude and/or your feeling with respect to the higher force.
The trigram interns higher represents the attitude and/or the feeling of your "superiors" or the company with respect to you.
