As an alternative to these major epistemological and philosophical trends Ferrer focuses upon the great variety, or pluralism, of spiritual insights and spiritual worlds that can be disclosed by transpersonal inquiry. In contrast to the transpersonal models that are informed by the "perennial philosophy" he introduces the idea of a “dynamic and indeterminate spiritual power.” Along these lines he also introduces the metaphor of the "ocean of emancipation". According to Ferrer "the ocean of emancipation has many shores". That is, different spiritual truths can be reached by arriving at different spiritual shores.
