The Major Arcana as representing the Journey of Life, as espoused by Mr. Edogawa in P3:<br/><br/>The first card, numbered 0, is The Fool. It represents the beginning and suggests infinite possibilities.<br/>The next card, The Magician, represents action and initiative...  but also immaturity.<br/>The Priestess represents contemplation and inner knowledge.<br/>The Empress represents motherhood and the life it brings forth.<br/>The Emperor is an opposing card.  It represents fathering and relates to leadership and decision-making skills.<br/>The Hierophant represents formality and knowledge, and stands for religion.<br/>The Lovers represents choice.  Here, the individual's consciousness has finally surfaced.<br/>The Chariot represents victory for the individual, but only a momentary one.<br/>Justice represents the knowledge of what is right and what is wrong.<br/>The Hermit represents the individual's search for answers by looking inward, deep inside his heart.<br/>Fortune represents fate, and the opportunities that come with it.<br/>Strength represents both passion and self-control. It is depicted as power with reason.<br/>The Hanged Man reflects the individual's inability to take action.<br/>Spiritual death awaits the individual with the thirteenth card, which is aptly named Death.  Death is considered a transitional card: the old ends, and the new begins.<br/>Now let us continue along the path, following the transition.<br/>Temperance is the balancing of opposites.  Opening his eyes to the world allows the individual to grow...<br/>...  and as The Devil represents, he then faces temptation.<br/>At The Tower, his values collapse on him. It seems as if he no longer has anything to believe in, but...<br/>...  he then finds a glimmer of hope, represented by The Star, and he is suffused with a serene calm.<br/>This bliss makes him vulnerable to the illusions of The Moon. Fears arise, and he follows the dim path in his heart with trepidation...<br/>...  but he is rewarded with a bright future, represented by The Sun, which signifies true achievement.<br/>Judgment awaits the individual at the end of his journey, as he looks back on the path he has traveled.<br/>The final card is The World, which represents the individual's full awareness of his place in the world.<br/><br/>There are a few other commonalities that appear among characters that share Arcana across games, but for the most part a character's Arcana in the game doesn't necessarily represent their<em>personality</em>so much as their<em>situation</em>.  The Hanged Man is an intensely negative card, for example, but that's not to say poor little six year-old Mako is a caustic little bitch who brings only misery and despair; she's just in the position of The Hanged Man in P3 because her parents are getting divorced and she's completely powerless to stop the inevitable outcome, much like a condemned man on the gallows.  Akinari, the young man dying from a genetic disease in P3, is not Death because Death isn't<em>about</em>dying--literally, anyway--he's The Sun because in his dying weeks he finds meaning in his short life.<br/><br/>The only cards that carry really strong implied personality traits are The Magician (immaturity), the Emperor/Empress (paternity/maternity; leadership), and The Devil (deception, cunning, seduction, etc.).  A few of them also carry certain association with other traits, though.  (The Chariot card, for example, is generally associated with fighters or athletes--people who compete, physically, at things.  The Hermit is generally associated with intellectuals and is sort of a good 'otaku' card.)
