A comprehensive exploration and restoration of Taoism’s original teaching • Draws on source texts of the Tao Te Ching and the Chuang-tzu for ways to achieve skills effortlessly through unity with the Tao • Explains how Taoism is a spiritual technology for deprogramming ourselves from socialization and dissolving the ego • Explores concepts of wu-wei (nonaction) and xiaoyao you (free and easy wandering in oneness) in order to realize our unfiltered true nature Giving readers a fresh take on the ancient philosophy of oneness, while at the same time restoring Taoism’s original teachings, Jason Gregory shows how to effortlessly align with the Tao. By returning to the source texts of the Tao Te Ching and the writings of Chuang-tzu, he offers wisdom to liberate us from the suffering inherent in a materialistic culture and reconnect us with our unfiltered true nature. Since the time of Lao-tzu and Chuang-tzu, we have navigated a world detached from the Tao. This detachment continues to expand due to external forces and information saturation. In contrast to Confucianism, which offers social morality, Taoism is essentially a worldview shaped by nature—a spiritual practice for releasing ourselves from imposed socialization and reactions of the ego. Jason Gregory shows that imposed socialization can impede the spontaneous flow that is central to the Taoist path—your true nature as it is with no filters. He explains that what we see is not reality itself but a world according to our conditioning. Taoism seeks to reunite us with our undifferentiated nature, dissolving the binary limitation of reason in our mind and achieving xiaoyao you, “free and easy wandering.” This book shows the way to become what Taoists call a zhenren—an authentic genuine person, the ultimate state of being.

Jason Gregory reveals the psychological and spiritual damage digital technology and social media are having on the human mind, and gifts you a digital free lifestyle to reclaim your health and sanity for a better world. Spiritual Freedom in the Digital Age demonstrates that even though we are more connected than ever before, we are subtly going insane and also diminishing our health. Even though we are more connected; the constant conflict in the digital world proves that we are more divided than ever. Spiritual Freedom in the Digital Age is an antidote to the digital problem.

Reveals a structured mind-body system for cultivating effortless action and intelligent spontaneity for peak performance Integrating the wisdom of the ancient sages with modern science, Jason Gregory explains how world-class artists and athletes reach peak performance--and how you, too, can harness this “lifestyle technology” to make your actions effortless, enjoy intelligent spontaneity, and reach optimal performance at a peak level. Drawing on modern cognitive science, Gregory explains dual process theory, which divides mental activity into two spheres: cold cognition, analogous with rational thought, and hot cognition, based on emotional intuition--a theory anticipated by ancient Eastern thought, especially the teachings of the Chinese sages. The author explains that peak performance is impossible to achieve by relying solely on cold cognition as it cuts you off from the energy reserves necessary to excel. He shows how the athletic concept of being “in the zone” is based on practices that have become energized by hot cognition and thus instinctive. Outlining a structured training system that blends hot and cold cognition, the author identifies four fundamental habits and routines that lay the foundation for a healthy embodied mind and mindful body and thus are essential for developing peak performance and success. He explains how these training methods are practical applications of ancient wisdom from Zen and Taoist traditions, such as wu-wei, as well as how they are supported by recent medical research. Building on the four fundamentals, he offers practices for cultivating physical and mental intelligence, fasting the mind, and harnessing creativity to achieve your desires. Gregory explains how, with regular practice, we can use the four fundamentals to create masterpiece days. And, as the masterpiece days compound, you build an unstoppable momentum where success is inevitable.

Details the mindfulness method of non-doing to cultivate intelligent spontaneity and effortless action. Merging Taoist philosophy, Hindu principles, and Confucianism along with scientific findings, Jason Gregory outlines the practice of wu-wei as a vehicle to realize our innate freedom, revealing that when we release our ego and allow life to unfold as it will, we align ourselves more closely with our goals and cultivate skill and mastery along the way. Equating “being in the zone” with a stillness of the mind, Gregory shares meditation practices coupled with yoga exercises from Patanjali that allow you to approach life with a mastery of acceptance, releasing deluded beliefs of how to achieve success that make your mind “sticky” and poised for conflict. The author shows how practicing wu-wei paradoxically empowers you to accomplish all that you desire by having no intention to do so, as well as allowing you to become receptive to nature’s blueprint for expressing beauty. Revealing wisdom utilized by renowned sages, artists, and athletes who have adapted “being in the zone” as a way of life, the author shows that wu-wei can yield a renewed sense of trust in many aspects of your daily life, making each day more effortless. As an avid wu-wei practitioner, he provides keen insight on how you, too, can experience the beauty of achieving an enlightened, effortless mind while reveling in the process of life’s unfolding.

Stop planning, stop comparing, stop competing, stop thinking, and just breathe deeply for a minute . . . Our undivided attention is something we are rarely able to give for reasons ranging from digital overload to the cultural conditioning of equating busyness with purpose. Just as you might choose a fast from eating to detoxify the body, the best way to overcome this modern mental overload is to periodically fast the mind. Drawing on the spiritual philosophies and meditative practices of classical yoga, Hinduism, Buddhism, and Taoism, Jason Gregory explains how fasting the mind directly impacts your habits and way of being in the world to create peace and calmness in your life as well as allow you to build a firm psychological defense against the increasing bombardment of distractions in our world. By fasting the mind we strip away the distractions and stresses of modern life and return to our original nature as it exists deep within. We become more consciously awake in every moment, allowing us to feel the real beauty of the world and, in turn, to live life more fully, authentically, and peacefully.

In this philosophical, psychological, and spiritual exploration of enlightenment, Jason Gregory addresses how to access the original spontaneous awareness we all came into this world with. He exposes the illusion that we must strive to reach enlightenment, uncovering how our yearning for future accomplishments, attachment to the past, and reliance on authority outside the self are social constructs that distract us from the reality of the now. The author explains how our original enlightened nature has been obscured by social, cultural, religious, and egotistical conditioning of the mind caught in time.

Explaining the process and energetics of Daoist internal alchemy, the author describes in detail the practice of Nei Dan, the alchemical firing practice of Daoism that has until very recently been a closely guarded secret.Drawing together a huge amount of esoteric material on the hidden aspects of Daoist practice, he presents theory and practice coherently for western practitioners. He offers his own experiences of each stage of attainment, describing the tangible results that should appear, and provides guidance on the practicalities and potential pitfalls of alchemical training.
