It is preferable to observe with the eyes than to drift aimlessly in the spirit. However, this too is futile and a daydream of the soul. Simmachus has effectively expressed this by stating, "it is better to strive than to drift aimlessly," implying that it is more beneficial to align our actions with the guidance of the intellect, often regarded as the spiritual eye, rather than to follow the desires of the heart. This aligns with what is articulated in Ezekiel, who speaks of those "who walk in the will of their heart." Additionally, it admonishes the arrogant and self-righteous by indicating that a person who considers all aspects is superior to one who values only their own achievements; indeed, nothing is worse than this last state, which is more empty than the wind.

Aquila and Theodotion rendered the term as "languishing of the spirit," translating it as "the grazing of the wind," while Simmachus referred to it as "brokenness of spirit." Notably, both spirit and wind are represented by the same Hebrew term, ruah.
