SOLVED. speculative fiction, meditator encounters future incarnation of himself [s]

[Shirley]

I read it in late 80s-early 90s, hardcover. A man on a spiritual quest finds a power spot in Hawaii and meditates there. The book follows his present-day life, interspersed with accounts of his mediation experiences. A man appears to him in his meditations, and the vision experiences get more and more complex. The man turns out to be a future incarnation of himself, living perhaps centuries in the future, after sudden rising sea levels have disrupted world trade, followed by total destruction of civilization-as-we-know-it. Iron and steel have become the most precious metals, because they can no longer be made - ore cannot be mined or transported, and technology for smelting has been lost, along with other technologies. (too early for internet to be mentioned, I think!)

Shirley left the group but she has told me that was the correct book. Moving to Solved.

Technically this is nonfiction - a spiritual autobiography - filing as such.
