Which Jewish mystical tradition emphasizes the unity and oneness of all creation?

The mystical tradition that emphasizes the unity and oneness of all creation is Kabbalah. This tradition seeks to explore the nature of God, the universe, and the relationship between the two, often focusing on the idea that all elements of creation are interconnected and stem from a single divine source. Kabbalistic teachings delve into concepts like the Ein Sof, which represents the infinite aspect of God, and the idea that everything in existence reflects this divine unity.

Kabbalah employs complex systems, such as the Tree of Life, to illustrate how the divine emanates into various aspects of existence. This profound connection highlights the belief that despite the apparent multiplicity and diversity in the world, there is an underlying oneness that links all creation back to its divine origin.

In contrast, the other traditions mentioned do not primarily focus on this aspect of unity in the same mystical framework. Hasidism, while it does incorporate some mystical elements and emphasizes a personal relationship with God, is more focused on joyful worship and community. Orthodoxy emphasizes adherence to traditional laws and practices without necessarily delving into the mystical insights that Kabbalah offers. Reform Judaism adopts a more progressive approach, often prioritizing ethical living and social justice over mystical interpretations.
