at first id like to start with a quote from Rollo May(http://en.wikipedia.org/wiki/Rollo_May); "You're are only anxious about things you value".
i think this is essential on understanding our inferior.
at this point i should explain the concept of shadow(personal, not archetypal).Ego is the conscious part of you.Originally Posted by http://www.nyaap.org/jung-lexicon/s/
functions arent either conscious(in ego) or unconscious(in shadow), they are partly in ego and partly in shadow, dom function takes bigger part of ego than inferior, therefore inferior is more in the shadow. others are something between depending how you have integrated them into your ego(learned how to use them/gotten conscious control over them).
self is the whole you, both ego and shadow. all of the functions have things they value, values can come from the shadow part of self or the ego part of self. now change the word "you" to self in that quote.
im pretty sure that all of us have had some sort of anxieties(big or small) about things we do not quite understand or see where it is coming from. those sort of anxieties come from the shadow part of self.
the fact that something causes anxiety to you is a sign that it has value for you, whether you realize it or not. if you just push things away that are causing anxiety to you, you are pushing things away that are valuable to you and inhibiting your development and in the end of the day, your well being.
this sort of anxieties that you do not consciously recognize where they are coming from, are the drives of the shadow, in most cases drives of the inferior.
so the next time something causes anxiety for you and you dont understand why, i suggest looking at it from your inferior(or tertiary) point of view. because you know, if it wouldnt be important for you, you wouldnt cause any anxiety.
