In 1320, German theologian Meister Eckhart began preaching about mystical theology, emphasizing the 'ground of the soul' and the necessity of detachment to experience the divine. His teachings challenged conventional religious practices and encouraged a more personal and direct relationship with God. Eckhart's influence on Christian mysticism and philosophy has persisted through the centuries, inspiring later thinkers and movements that sought to explore the nature of spirituality.

Meister Eckhart's mystical theology and paradoxical language influenced metaphysical poets who explored the depths of spiritual experience. His ideas on inner emptiness and divine union resonated in the works of later poets, shaping modern mystical literature.
