In his visionary work on the natural and sacred spheres, New Thought pioneer, Henry Drummond, started to bridge the gap between science and spirituality. He explained how modern laws of physics, biology, cybernetics and ecology are the same laws that govern the spiritual realm. He showed how various scientific findings may be applied to seemingly divine human experiences. For Drummond, this realisation meant we could live freely, not bound by a limited view of the universe in which only matter could be manipulated. The sixth addition to Ruth Miller's Library of Hidden Knowledge series, ONE LAW updates Drummond's amazing work into accessible, modern English alongside the original text. This format provides a clear interpretation that cuts through Drummond's difficult, outdated terminology, helping us understand the often opposing - but overlapping - scientific and spiritual realms. Miller, an ordained New Thought minister, integrates up-to-date scientific, spiritual and cultural information to clarify important metaphysical principles and bring Drummond's philosophy to all who seek its truth.
