Progressions contain the primary timing for your development and growth and show how you evolve and grow. They are generally felt internally. You may make external changes based on them, but they are like the unfolding of your astrological DNA. The timing for all of these changes is very personal, based solely on your own chart. Because evolution is slow, these are slow changes.
Your progress chart is different from your birth chart in that it moves each planet by its amount of daily travel for each year of life after the person is born. Progressions show how you evolve and develop over time.
