You already know that there are six profile types, but do you know what you have two numbers? No, it’s not because you might want a backup in case you don’t like the first number you get! These numbers are both important and they both describe very important facets of your personality.
The hexagrams (of six lines) amount to a pair of trigrams (of three lines). The lines each represent yin or yang in infinite combinations. The bottom 3 lines, called the lower trigram (Line 1, 2, 3) are interpersonal lines. These energies represent your own personal karma and evolution. The top 3 lines or upper trigram (4,5,6) are transpersonal energy. You learn it with others, and through relationships.
