The number 7 is a seeker of truth that does not take things at face value, always seeking to understand underlying realities and hidden truths as it knows that not everything is exactly as it seems. The 7 contains elements of both the skies/soul and earth/body and is connected to concepts like the 7 colors of the rainbow, the 7 days of the week, the 7 notes in the musical scale, and the 7 circles in the Seed of Life symbol. The number 7 appears frequently across many systems and traditions.
