Each verse is commented profusely, and clearly, the author knows of what she speaks.
At the end, is presented without going into details, some uses verses coupled with yantras (mystical diagrams) and offerings to create changes in his life. But nothing in the absolutely necessary.
The recitation of the text, or a particular verse that speaks is a separate practice.
The explanations give profound keys to Tantric tradition, such understanding of the ascent and descent of the kundalini, which means a deep sense Shiva and Shakti, the keys to better understand the realities indicated by the verses .. .
Contains text translation aglais, Devanagari and a phonetic transcription for a recitation in Sanskrit.
I recommend this book that covers a certain depth. It is in English.
