Part 2/7:
Initially among the Ainur, Sauron possessed the power that allowed him to take multiple physical forms. As celestial beings, similar to other Maiar and Valar, the Ainur had the capacity to assume diverse appearances when they descended into Arda. The “Ainulindalë,” a sacred music that birthed the world, witnessed their vision of the Children of Ilúvatar—the Elves and Men—before they materialized in time and space.
In Arda, the Valar adopted forms reflective of their grand vision, choosing physical representations of masculinity and femininity. However, they could also manifest in other shapes or even remain invisible. In this regard, they possessed a freedom that transcended mere physicality, utilizing forms more as adornments than necessities.
