The judgment
James Legge
Critical Mass depicts a weak beam. Under such conditions it is advantageous to move in any direction whatever. Success is indicated.
The six lines
R.L. Wing · line 1 is at the bottom
- Line 1Yin
When embarking on an important endeavor, it is necessary to pay particular attention to details at the beginning. The times are indeed extraordinary, and you must be particularly careful to proceed in the right way. Being overcautious is not a mistake.
- Line 2Yang
Look to those who are modest in attitude, or are beginners themselves, to help you in your endeavors. This way you are in the company of persons who can understand and share the enthusiasm of your goals. Things will move smoothly and the situation will become revitalized.
- Line 3Yang
You are inclined to force your way forward when, in fact, there are obstacles that cannot be overcome in this way. Even worse, you cannot accept advice from others because it is not what you wish to hear. Misfortune will inevitably follow.
- Line 4Yang
You can now find within yourself the strength and vision to achieve a successful outcome in your endeavors. Do not rely upon people or things outside of your Self for guidance. Dependence now on external things leads to humiliation.
- Line 5Yang
In critical or significant times it is exhausting to cling to your ideals and ignore the realities of your environment. These realities are the superstructure that supports your life. If you ignore your foundations in your reach upward, you will become unstable and accomplish nothing at all.
- Line 6Yin
The goal is worth accomplishing, although the sacrifice to attain it may be confounding in its enormity. No blame is attached to such action, although you should realize the extraordinary reality of what is happening.
