The existence of multiple races and ethnicities can be seen as part of the diversity of human experience and spiritual development. Each race and ethnicity represents different aspects of the human experience, often influenced by geographical, cultural, and historical factors. From a spiritual perspective, the diversity of races can be seen as a reflection of the variety in the spiritual journeys of individual souls, each having its own lessons to learn and experiences to undergo.
The purpose of this diversity is likely connected to the idea of growth, adaptation, and the expansion of consciousness. Each group may offer unique insights, wisdom, and strengths, contributing to the collective experience of humanity. Spiritually speaking, it's important to see all races and ethnicities as equal and worthy of respect, as they all have the potential to connect with the divine in their own ways.
So, in essence, multiple races exist as part of the divine plan for variety, balance, and the progression of human beings on their spiritual path.
