It's a popular self help book out there,
It's essentially about how 🤔 to realise your personal goals in life in a bigger picture Holistic way type of thing,
Could come across as a bit spiritual aspect them running through the book,
i have heard of the book and have got it second hand charity shop,
It's sounds very much like your ex was being passive aggressive patronising know all type or type of thing,
However don't let the intention behind him giving you this book get to you, put you off..
have a read of it if you want to?
See what you think of it and how it can potentially help you,
if you feel like that about this book,
If you are just not feeling it about this book in whatever way?
then just donate to a charity shop or pass it on to someone else a friend etc who you know will apreaciate a book of this kind in some way..
