A case study that slowly turns mystical — Weiss begins as a conventionally trained, skeptical Yale‑educated psychiatrist treating a woman named Catherine for crippling anxiety, nightmares, and phobias. When hypnosis unexpectedly pulls her not into childhood but into vivid past‑life scenes, and her current symptoms begin to vanish after each regression, he’s forced to follow the evidence into reincarnation, soul lessons, and messages from non‑physical “Masters.”​

He combines clinical rigor with a calm, matter‑of‑fact tone as he describes phenomena — reincarnation, soul guides, between‑lives spaces — that he never expected to encounter, which makes the story feel grounded rather than sensationalized.

What you can get from reading it

• A front‑row seat to how past‑life regression sessions actually unfold — the language, imagery, and emotional release that arise when Catherine “drops into” other lifetimes.​
• A sense of how seemingly irrational fears (water, darkness, enclosed spaces) can map to unresolved traumas from other eras, and how revisiting them can dissolve symptoms in the present.​
• Exposure to the “space between lives,” where Catherine channels teachings from advanced beings — the Masters — around love, forgiveness, karmic learning, and the continuity of the soul.​
• A lived example of science meeting the mystical: a by‑the‑book doctor wrestling with data that doesn’t fit his model, modeling how to stay curious instead of shutting down.​
• Gentle but profound reframes around death, suffering, and destiny, leaving you with a wider sense of your soul’s journey and why certain relationships or challenges feel charged.​​
