If the guy you're dating had on his bedside table a self-help book by the likes of Osho or Dr John Demartini, would you think he was profound or a total loser?
Personally the warning bells would start clanging loudly in my brain. And I tried reading both books, believe me, but there was no breakthrough experience for me and I gave up after 30 pages. I would rather see, say, a hefty Yves Saint Laurent tome by his bedside; at least I'd know he's gay and we could spend the rest of the night watching Sunset Boulevard and taking turns acting out Norma Desmond's lines.
