Your personal birth chart is the window to the universe at the moment you were born. We take your birth time and place and see where the planets, the major asteroids and the north and souths are. For events, I bring my ephemeris (the book where all the planets locations are) and look up your approximate planetary positions. It's quick and provides us with enough information to see what the planetary transits are.
Each card tells a story, and the story unfolds as all the cards are drawn and position themselves around your first card, which represents you. For events, I usually do short readings, 5 to 7 minutes, only 3 cards if you have many guests. For individual sessions, we could spend a few hours delving into the cards and doing an astrological chart for you.
