Your natal chart is a snapshot of the way the sky was when you were born. It shows all the energies at play in the cosmos at the time of your birth. The macrocosmic dynamics at the time of your incarnation are reflected in the microcosm–YOU.
Know thyself: it is one of the most important things you can do. When you know yourself, you can begin to change the world.
Divination is a useful tool to read the energies surrounding a given situation for greater clarity & insight. A tarot reading shows the dynamics currently at play, what you & others contribute to a situation, and any possible future outcomes that can be influenced by your vision and choices in action.
