Interpretation: That which is small and seen as weak and insignificant will triumph over larger forces. It’s just like David and Goliath, or like other fables and tales that explain that that which is sometimes considered to be a weakness may turn into a strength if we know how to make use of our assets.
It is thus important to pay particular attention to detail, be more perfectionistic, and cultivate your adaptability so as to be able to tame any significant changes as they occur.
This is not the time to take action using force, but rather with finesse, intelligence, subtlety, and even some degree of cunning, staying hidden and covered as you advance, presenting yourself as harmless, and concealing all or a part of your deeper intentions.
Astrological points to pay attention to: This may for example often be found in the Virgo/6th house archetype, as these people instinctively have this eye for detail, improvement, and optimization and know quite well how to intelligently adapt to things and find clever solutions to problems (we often find that they are particularly good craftspeople), giving intelligent aid to those around them without necessarily wanting to actually get noticed themselves.
In a way, this hexagram very much accentuates intellectual forces and thus the planet Mercury and the aspects that it may form in transit or in your birth chart, in terms of analytical capabilities, logic, pragmatism, and your practical side.
Forces related to Pluto may also come into play when it comes to the hidden/concealed/cunning aspect here.
This hexagram may ask you on a more fundamental level to take stock of all of the energies in your birth chart and determine where it is that you feel “weakest,” because this may be a strength and a positive attribute when confronting the present issue.
Remarks: This hexagram is very closed off and the only hole is tiny, like the eye of a needle, so whatever wants to get inside needs to show itself to be humble and thoughtful, because brute force will be entirely useless here.
