Blueprint for Immortality: The Electric Patterns of Life by Harold Saxton Burr (1972) presents a comprehensive, scientific account of electrodynamic fields ( L 𝐿 -fields) that control all living things. Burr argues that these measurable electrical fields act as a blueprint, organizing physical development and determining the health of organisms. The book is considered a foundational text in the study of bioelectromagnetics, bridging the gap between philosophy and scientific biology.
