The First Six is the first line of The Army hexagram — a yin line in the lowest position. 'An army must set forth in proper order' establishes the fundamental principle: before any collective action, there must be clear rules, strict discipline, and proper organization. 'If the order is not good, misfortune' warns that even the most righteous cause will fail without proper structure.
As the card depicts — soldiers standing in perfect formation, each knowing their place and role. This is the foundation upon which all military success is built. In your situation, before you mobilize others or launch any major initiative, ensure that the rules are clear, the roles are defined, and everyone understands the plan.
