Currently, I am reading the very excellent book Shakti Rising.
This book is an excellent voyage into the different aspects of Shakti energy as well as the goddesses who embody those specific facets. Philosophically, the book covers the necessary points of tantric and vedantic philosophy in a way that is both deep and grounded. More importantly, the book offers a series of key explanations and exercises for how to work with both the light and shadow aspects of each goddess. Each Shakti facet is analyzed in terms of how the energy can either help or hinder our actions as we deconstruct the i-self.
As we are all embodiments of Shakti, I recommend this book to everyone and anyone. I have found it not only instructive in where I block specific energies and motivating to move deeper into these energies in physical and devotional ways.
