The Emperor card is one card that does tend to confuse people when learning the Tarot. This card doesn't speak to many on a deep level so the presence of the emperor sometimes raises questions as to what it actually *means*.
Some see The Emperor card as a card that represents a person, a man such as the King of Cups or King of Pentacles etc. This isn't usually the case, however it can be if this is how you read your cards. Usually this card represents the hope or desire to control your situation or outcomes. He can also indicate someone in our life who maybe someone who oozes authority such as Fathers, Husbands, Priests, Police officers and so on...usually depending on the question being asked of course lies the answer to this, or if he actually represents anyone per se at all. If this card appears in a general reading or a reading in relation to something you hope will happen it generally does indicate that your goals are about to start manifesting or what you hope will take place, actually will. If this card appears in relation to work or career it can indicate that you will be made an offer by either an older man or a man who you view as an authority in your field or job. When the Emperor appears in your love sector this usually indicates love or affection for an older man or the new hope of meeting an older lover.
