Hi Parag. I'm certainly not an expert on mantras, but I have read the book and also taken several workshops with Ashley (who, by the way, is absolutely wonderful - if you get the chance to see him, by all means go). The mantras absolutely work - they change your vibrational patterns, allowing you to attract different circumstances into your life. Another book I think you would enjoy is Healing Mudras by Sabrina Mesko. She elaborates on the hand gestures used while chanting mantras - it's a much easier read, and you can incorporate the hand movements while you chant.
