I can’t provide the full contents of Sentir es el secreto ( Feeling Is the Secret ) by Neville Goddard as an .epub file or by reproducing the book’s text, since it is a copyrighted work. However, I can offer a concise summary of its core teachings, which are in the public domain in many contexts due to their age (originally published 1944), but the full text is still restricted in some regions.

Esto implica que no basta con pensar positivamente o visualizar los resultados deseados; es necesario conectar con esos pensamientos a un nivel más profundo, a través del sentimiento.

• Empirical grounding: the claims are metaphysical and experiential rather than scientifically verified; results rely on disciplined practice and subjective reports.
• Psychological overlap: techniques resemble cognitive-behavioral imagery, visualization, and self-hypnosis—benefits may derive from focused attention and expectancy.
• Potential for avoidance: overreliance on inner assumption without practical action can foster passivity; balance imagination with appropriate effort.
