    You can become Christ within this human life and learn to embody all that is good within you. I came to show you the beauty of your own soul and what is possible as a human. I came to show you that it is possible to be both human and divine, to be love incarnate. You are equally both. You walk with one foot in the world of form and another in the Formless. This mysterious duality within your being is what this book is about.” "The consciousness that is within me is also within you. You are the son as equally as I am. You are the ‘I am’ I spoke about. You and I are one. You and everyone else are one. Many are ready for the Christ within to come forward and manifest in the world more fully. The birthing of this Christ—of Christ Consciousness—is the true second coming. ‘Christ Consciousness,’ as I am using it, points to the divinity within everyone and the potential for that divinity to become a living reality, to become what lives you. I was an example of that possibility in my lifetime two thousand years ago.” This book was given to Gina Lake by Jesus. It is part of a series of books, including A Heroic Life and The Jesus Trilogy. You will learn: • How to embody the divine self in the world • How to tell when you are identified with the ego • How to spot the ego in your thoughts and conversations • What kind of thoughts are in the thought-stream • How to disidentify from the ego • How to be in your body and senses • How to move into Presence and stay there • How to be present while speaking and acting in the world • Spiritual practices that support Presence • What embodiment, enlightenment, self-realization, and awakening are • Pitfalls on the spiritual path • How to be with emotions • How to be with and heal energetic blocks in the body • How to overcome bad habits and addictions Review from David Fishman, teacher of A Course in Miracles: "I love this book! It's a perfect companion to all students and teachers of A Course in Miracles, for it encompasses the core themes and values of ACIM in a simple format that provides practical guidance for everyday use.

    Intended for developers who are already familiar with the Apex language, and experienced Java and C# developers who are moving to Apex, this book starts where the Force.com documentation leaves off. Instead of trying to cover all of the features of the platform, Advanced Apex programming focuses entirely on the Apex language and core design patterns. You’ll learn how to truly think in Apex – to embrace limits and bulk patterns. You’ll see how to develop architectures for efficient and reliable trigger handling, and for asynchronous operations. You’ll discover that best practices differ radically depending on whether you are building software for a specific organization or for a managed package. And you’ll find approaches for incorporating testing and diagnostic code that can dramatically improve the reliability and deployment of Apex software, and reduce your lifecycle and support costs. Based on his experience both as a consultant and as architect of a major AppExchange package, Dan Appleman focuses on the real-world problems and issues that are faced by Apex developers every day, along with the obscure problems and surprises that can sneak up on you if you are unprepared.

    Simultaneously becoming more user friendly and more powerful as a back-end system, Linux has achieved new plateaus: the newer filesystems have solidified, new commands and tools have appeared and become standard, and the desktop--including new desktop environments--have proved to be viable, stable, and readily accessible to even those who don't consider themselves computer gurus.
