A Commentary on Theologia Germanica
Discover the Forgotten Christian Classic That Reveals the Non-Dual Heart of Christ’s Teaching
Theologia Germanica is one of the purest expressions of Christian non-dualism ever written. In this illuminating commentary, Swami Nirmalananda Giri — a monk deeply rooted in both Christian mysticism and the wisdom of India — unveils its timeless message: the false self must die for the divine Self to be known — a truth as central to Advaita Vedanta as it is to the teachings of Jesus.
This 14th-century mystical masterpiece by an anonymous mystic of the Teutonic Orderhas gone through nearly 200 editions but is almost unknown today. It teaches that true blessedness lies “not in much and many, but in One and oneness.” It echoes the wisdom of the Upanishads, declaring that the soul must transcend its “I” and “mine” to be filled with God.
What You Will Learn
- The striking parallels between Christian mysticism and Advaita Vedanta
- Why “putting off the creature” is essential to knowing God
- How the soul’s “I” must decrease for God’s “I” to increase
- How to go beyond belief into direct, inward realization of the Divine
- Why true love seeks only the Good for its own sake — not reward
Who This Book Is For
- Seekers of non-dual wisdom from East or West
- Readers of The Bhagavad Gita, The Cloud of Unknowing, or Meister Eckhart
- Christians exploring the deeper contemplative path of Christ
- Yogis and meditators drawn to the mystical core of Christianity
- Interfaith readers looking for unity between Advaita and Christian spirituality
This is not academic theology. This is a practical guide to spiritual transformation.
What Readers Say
“This book sheds new light and provides a fresh perspective on a mystical world that seems almost forgotten…Highly recommended for readers interested in Christian mysticism and non-duality, offering a contemplative exploration of divine union and spiritual transformation.”
~Stefan Kaiser
“It’s an inspiring glimpse at a Western figure’s grasp of the non-dual view of God and man, something more likely to be encountered in ancient Indian philosophy…Don’t think that this is a dry, depressing series of lessons. There is a ton of wit and humor from Nirmalananda, who’s always full of hilarious anecdotes from his own life.”
