Line-1Legge: The first line, dynamic, suggests the idea of grass pulled up, and bringing with it other stalks with whose roots it is connected. Advance on the part of its subject will be fortunate.
Wilhelm/Baynes: When ribbon grass is pulled up, the sod comes with it. Each according to his kind. Undertakings bring good fortune.
Blofeld: When grass is uprooted, what is attached to it is pulled up as well. It is an auspicious time for advancing according to plan. [This would seem to mean that we are likely to get what we seek plus something more.]
Liu: When ribbon grass is pulled out, its roots come with it: they are of the same kind. Undertakings lead to good fortune.
Ritsema/Karcher: Eradicating thatch-grass intertwined. Using one's classification. Chastising significant.
Shaughnessy: Plucking the cogon-grass stem with its roots; to be upright is auspicious.
Cleary (1): When pulling out a reed by the roots, other roots come with it. It is auspicious to go forth.
Wu: Like pulling up reeds with all their connecting roots, advancing will be auspicious.
COMMENTARYConfucius/Legge: His will is set on what is external to himself. Wilhelm/ Baynes: The will is directed outward. Blofeld: The mind is outward looking (i.e. fixed upon the people's welfare.) [This really means the mind of the Superior Man, whose duty it is to look after the people’s welfare. If he is truly a Superior Man, when his mind is turned inward it is to meditate upon and eradicate his faults; when outward turned, it is concentrated upon his duty to the ruler (provided the king is worthy) and his care of the people.]Ritsema/Karcher: Purpose located outside indeed. Cleary (2): Means focusing the will beyond. Wu: Because the aspiration is to go upward.
Legge: The symbolism of the first line is suggested by the three dynamic lines of the lower trigram, all together, and all possessed by the same instinct to advance. The movement of the first line will be supported by the others, and will be fortunate. "He has his will set on what is external to himself" means that he is bent on going forward.
Line 1 Pulling out grass, entangled roots = each according to its kind. Changes to (46) Pushing Upward. In order to succeed, you may need the help of people of like mind. Any changes may reveal that under the surface things are more entangled than had first appeared. Proceed anyway. Honor differences in another and don’t try to change them. Actions that you take will be beneficial for all. This is also the idea of ‘grass root’ gatherings or uprooting something as a way of weeding out the confusion so new growth can emerge.
