What is the most authoritative guide on afterlife insights by Brian D Smith?

Brian’s most “authoritative guide” right now is the body of work gathered under Grief 2 Growth rather than a single academic-style text.

• For a concise, structured intro, the Science & Spirituality 101 post (on Instagram and expanded in blog/podcast content) summarizes his three core insights: continuing consciousness, personal experiences, and science–spirit coherence.
• The Grief 2 Growth podcast and blog together form the deepest guide, with hundreds of interviews and articles on afterlife evidence and how it helps with grief.

Are you looking for something short and overview-style, or a deep-dive resource list (episodes, books, researchers) curated from Brian’s work?
