Mr. Howard presents a Taoist philosophy adapted for Western tastes. He states (repeatedly) that his Mystic Path is a way to happiness and serenity. And he provides some general guidelines on how to achieve this such as self-observation, suppression of the ego, detachment from worldly things. But he provides little in the way of step-by-step exercises or concrete practices to perform. I liked the book a lot but it had a bit of an air of promotional literature for his in-person lessons.
He references many books and mystics by using quotes and footnotes. These references could be a starting point for deeper study of the matter. The book has no index making it a challenge to use as an in-depth guidebook. The table of contents is quite detailed though.
He never defines what is meant by the term "Cosmic Power" in the title. But judging by the book's contents I think he means power over oneself.
The author's theory is that we're composed of two internal entities, our False-Self and our True-Self. This is a simplistic version of more complicated psychological explanations of our internal life (or life of the mind). The False-Self represents everything that is sinful, evil, hateful, stupid or corrupt. The True-Self represents everything that is good, calm, peaceful, content and happy. The basic idea of the book is to minimize or eliminate the False-Self in your life, thereby allowing your True-Self to take over. The author asserts that this is the mystic path to lasting happiness.
The False-Self can be eliminated by observing it, understanding it and disassociating oneself from it. You can say that any bad thing you did was not done by you (i.e. your True-Self) but, rather, it was done by your False-Self (i.e. the devil made you do it). Therefore, you need never feel bad about your evil, sinful or stupid actions because they are all the fault of your False-Self. Those actions aren't really “You”. You should dispassionately observe and understand your False-Self's actions. This will allow your True-Self to reveal itself and act in the future. So all of your worries, fear, guilt and shame will fade away to be replaced by the happiness and right-action of the True-Self.
Similar remarks are made about dealing with tragedies and catastrophes in your life. You should disassociate yourself from them. They have nothing to do with the inner, soulful life of the True-Self. And any bad feeling you have about anything has nothing to do with the exterior event and everything to do with your reaction to it. If your reaction is to be glad or indifferent to a catastrophe then you can be happy no matter what happens.
Obviously, the above is a bit difficult to put into practice in the real world. That's why the author urges the practitioner to be persistent in walking the mystic path and to wait out difficulties.
I think that if you can do the above you will be persistently happy and content but also a bit like a zonked out zombie who is selfishly indifferent to everything but their inner mental life. I like the idea of being happy all the time (I give it five stars for that) but I'm a little repelled by the thought that it may come at the cost of discarding morality and compassion toward others. And, of course, it's entirely possible that I don't fully understand what the author is trying to say. I think I'll reread the book later and also check out some of the other authors that he mentions (like Thoreau and Ralph Waldo Emerson).
