Steadfastness
B”H
yesod shebbe malchus
(foundation within sovereignty)

A strong foundational belief system is necessary in order to maintain a sense of autonomy. Without reference points, in regard to one’s identity, it would be too easy to be swayed by this, that or the other opinion, trend, or viewpoints of others. A tenacious adherence to a set of values, beliefs, or overall conception of oneself will be a fence around an individual’s autonomy.
Otherwise, we would be subject to drown in a sea of nihilism, where values do not matter, and life has no directive towards an ultimate purpose. G-d forbid. Therefore, to cling to the truth through deveykus is paramount not only to connect to G-d, but to also remain steadfast on the derech (path) of life.
