The Hermit

Basic meanings - Soul-searching, introspection, being alone, inner guidance
The Hermit does everything with a deliberate, conscious approach - knowing that each step of the journey is a small imprint upon the larger picture of his path. The Hermit has had to learn this lesson by means of distancing himself from the regular, routine world. In this way, he is able to listen to the inner stirrings of his own intuition and act upon it.
However, by purposefully choosing to remove himself from society he also runs the risk of being misunderstood and labeled inappropriate. These labels do not concern him as his path of spiritual knowing and higher wisdom are his prime concerns.
The Hierophant

Basic meanings - Religion, group identification, conformity, tradition, beliefs
Foremost, the Hierophant is a vehicle for religious knowledge. Although, he differs from the High Priestess. Where she is the holder of esoteric knowledge for the sake of holding - the Hierophant is the keeper of religious content for the sake of presentation. The Hierophant has an enormous responsibility because he stands as a religious icon to the people.
The Hierophant is certainly a master of esoteric wisdom - incredibly well-versed and educated in the ways of [the] spirit. However, he is bound by tradition, ceremony, and committed to presenting himself in a manner that is suitable to the ideals of the people to which he preaches.
He wields great power and is ever in-check not to abuse this power. He is consistently conscious of his responsibility to the people, and his mission to present the word of God in an honest, true, accurate manner.
The Tower

Meanings - Disaster, upheaval, sudden change, revelation
Changes in life are typically gradual. When a sudden, cataclysmic change occurs, such as the Tower card suggests, it is an anomaly of sorts. Such a drastic upheaval means the Universe is trying to wake us up from our zombie-like state. This wake-up call comes in the form of an event that blind-sides us and shakes us out of the fog we've been living in.
An interesting observation about this card [in certain renditions] is its movement. This symbolizes that the signs have been all around us. However, we continued to sit in our "tower" or to construct our lives based on errant thinking, all the while the storm is brewing. So in actuality, the changes foretold in the Tower card aren't so sudden, we were just too blind to the signs. We refused to admit the problems. We simply turned away.
