This book deals with powerful sacred mantras of different Hindu deities and their blessings. These energy based sound, syllable, word or group of words mantras when chanted with faith, patience and devotion create energy vibrations that can replace negative energy with positive one eventually leading to a peaceful quiet mind; and positive and beneficial results. There is now growing evidence that repeating a mantra is good for mental health. The individuals who are in stressful situations are able to cope better with stress by using a mantra. Even those who see themselves as not having any religious affiliations can still benefit from mantra because it has spiritual significance.I decided to write about mantras firstly because of my own experience of using them as tools to help me not to ponder over negative thoughts but to find peace, solace, create positive energy and thoughts; and face the challenges of everyday life. Chanting of mantras has allowed me to conquer my mind. Secondly, over the years, I found it extremely difficult to find a book of mantras along with sufficient description of the prominent Hindu deities. After looking into the matter extensively, I discovered that a large number of Asians outside India are looking for the same in a book form so that they can carry or keep the book with them.
