Who you are at your core. Set by your birthday. The one you already know.
How you feel and what you need. Set by the day and time you were born.
The first impression you make. Set by the exact minute and place. This is why we ask for birth time.
A planet looks like it moves backward. A review period, not a curse. Back up your files anyway.
A map of the whole sky the moment you arrived. Your sun sign is one line of it. We read the whole page.
That's it. That's the syllabus. The rest is attitude.
