Frequency. The Power of Personal Vibration (Penny Peirce)
For one or other reason it took me more than a year to read this one:) Not that it is such a heavy scientific stuff; it's much more about learning to recognise and to feel your own home frequency. Probably this feeling part made it so tough:))
From this book you learn that we are all moving to the Intuition Age, away from the dominance of the Western mechanistic paradigm and that there're different stages in this proces (and not the end of the world, as it feels from time to time) through which we're all moving. It's then interesting to see in which stage you actually are at this moment, what can you expect and how to make your own transition smoother.
This book is just full of brilliant insights, such as "It's up to you how you want to feel and who you want to be. No one else can create the conditions for you to feel good if you haven't decided to feel good" and a lot of tools to accelerate your awareness.
Enjoy and transform!
