Spirituality seems to be in the NF wheelhouse.
From Kiersey's Idealist Overview
All that abstraction (N) couple with the Feeler thing. Seems pretty straight forward to me.Idealists (NFs), as a temperament, are passionately concerned with personal growth and development. Idealists strive to discover who they are and how they can become their best possible self -- always this quest for self-knowledge and self-improvement drives their imagination. And they want to help others make the journey. Idealists are naturally drawn to working with people, and... are gifted at helping others find their way in life, often inspiring them to grow as individuals and to fulfill their potentials.
It's not that other types can't be spiritual, but there is a unique quality to NF spirituality, I think. It's very much a part of their core worldview. It's very abstract. It's very much a driving force in their personalities.
