Think Like a Monk!
I came across this wonderful book by Jay Shetty called Think Lika a Monk! If you want peace and harmony in your life that is not "other" dependent and if you want to achieve "peaceful Independence within" then this book maybe right for you.
It comes in book and audiobook format and it is one of the bestsellers. Also, you will be able to practice its teachings as they are secular and does not limit to any religious or spiritual beliefs.
As always, take what you feel is right and leave the rest.
May everyone has happy and healthy life ahead!
Love and Light
