Game engine architecture

Combines cognitive psychology with Zen, Taoist, and Vedic practices to empty the mind • Explains how eliminating external stimulation can alleviate stress and anxiety for a calmer state of mind • Details meditation practices, such as open-awareness meditation, contemplation of Zen koans, and Vipassana meditation, and explores methods of digital detox • Draws on classical yoga, Hinduism, Buddhism, and Taoism as well as cognitive science to explain how and why to fast the mind 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. Applying psychology and cognitive science to samsara--the cycle of suffering created by our attachment to the impermanent--he explains how overreliance on the rational mind causes imbalances in the autonomic nervous system and suppresses our natural spontaneity, feelings, and intuition. When we are unable to relax the mind deeply, we enter a destabilizing state of stress and anxiety and are unable to liberate the true Self from the impermanence and limitations of the material world. Sharing Zen, Taoist, and Vedic practices to help you empty your mind and gradually restore your natural rhythms, the author shows how to give the mind time to truly relax from stimulation so it can repair itself and come back into equilibrium. He details simple meditation practices that are easy to implement in daily life, such as open-awareness meditation and contemplation of Zen koans, as well as the advanced techniques of Vipassana, a Theravadic Buddhist discipline centered on seclusion from all worldly stimuli. He also offers methods for digital detox and ensuring a good night’s sleep, a major support for healing cognitive impairment and restoring a state of equanimity. 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.

Are you going to uphold the status quo and participate in the eventual annihilation of the human race? If the answer is yes then close the book now and go on about your day as if this never happened. If you are still here then I must congratulate you for choosing the alternative. The alternative choice we are faced with is not some system or revolution which will guide us in a different direction. It is a path; it is a journey to explore who we truly are.A journey to understand our inner and outer worlds within ourselves which will guide us to our next step in our eventual evolutionary process. It is within this book where we will travel along the path together, but let me assure you that this journey is no leisurely stroll beside a pristine lake. The journey is a rough road that will shake the foundation of the way we perceive the world to its inner core.The path is not paved out of marble stone, so it is not meant to be easy. But if you can persist along this rough path it will eventually manifest into the beautiful path which you envisioned. The path we are on together will give you a better understanding of why our world is the way it is at the moment, where we are going, who we are and why we are here. The journey through the pages of this book may give you the sense of how we can achieve this peaceful world which we have all longed for.

Humility, being open and receptive to all experience, is the key to becoming one with the spontaneous patterns of the universe • Integrates classic teachings of Hinduism and Buddhism with principles of quantum physics to reveal the science of the enlightened masters • Reveals how we are each capable of shifting from the aggressive path of the warrior to the humble path of the sage • Explains how the key to catching the current acceleration of conscious evolution is humility From Krishna and Lao-tzu to Buddha and Jesus, each enlightened master discovered how being receptive to all experience was the key to becoming one with the universe and its spontaneous patterns of order and chaos. Revealing humility as the purest expression of this receptivity, Jason Gregory integrates classic teachings of Hinduism, Buddhism, Taoism, and Hermeticism with principles from quantum physics to explain the science of humility as practiced by the ancient masters. The author shows how, driven by fear, the human mind creates the ego. In its greedy and arrogant quest to protect the self and its desires, the ego forges the illusion of separation, weaving complex patterns of reality that shield us from our unity with all beings and result in attitudes of aggression, selfishness, and competition. He reveals how the iconic clash between this complex, aggressive “path of the warrior” and the simple “path of the sage” is reflected in the polarized state of the modern world. Yet this state also reflects the accelerating wave of conscious evolution we are now experiencing. The key to catching this evolutionary wave is humility: the reversal of complexity into simplicity, the ancient science of mental alchemy that represents the Great Work of Eternity.

The Path to Ultimate Freedom

The Science and Practice of Humility

Grazie alla psicologia e alle scienze cognitive, Jason Gregory dimostra come l’eccessiva dipendenza dalla mente razionale e l’attaccamento a ciò che è impermanente generi sofferenza, sia causa di squilibri nel sistema nervoso autonomo e sopprima la nostra naturale spontaneità, i sentimenti e l’intuito. Quando non riusciamo a rilassare profondamente la mente, entriamo in uno stato di stress e di ansia, ma grazie a pratiche zen, taoiste e vediche possiamo svuotare la mente e ripristinare gradualmente i ritmi naturali, imparando anche a rilassarci e a ritrovare l’equilibrio. Semplici tecniche di meditazione, facili da svolgere nella vita quotidiana, come pure tecniche tradizionali di Vipassana, aiutano a creare un sano isolamento da tutti gli stimoli del mondo moderno, attingendo a un serbatoio interiore di serenità e equilibrio. Con Digiuno per la mente impariamo a eliminare le distrazioni e gli stress; torniamo alla nostra natura originaria; diventiamo più consapevoli in ogni momento; percepiamo la vera bellezza del mondo e viviamo la vita in maniera più piena, autentica e serena. Scopriremo anche metodi efficaci per la disintossicazione digitale e garantirci un sano riposo notturno.

Digiuno per la mente

A guide for achieving an enlightened mind through the art of non-doing • Details meditation practices, focused on stillness of the mind, along with Patanjali’s yoga methods to maintain a consciousness referred to as “being in the zone” • Builds on Taoist, Confucian, and Hindu principles along with scientific findings to support wu-wei--the art of non-doing, non-forcing--as a way of life • Explains how wu-wei practitioners cultivate intelligent spontaneity and effortless action to allow the natural harmony of the cosmos to prevail The practice of non-doing, non-forcing is an essential aspect of Taoism known as wu-wei. Attributed to the great sage Lao-tzu, the philosophy of wu-wei teaches you how to develop a natural state of consciousness not bound by thought or preconceived limitations. Experienced by the greatest artists, athletes, musicians, and writers, this heightened state of consciousness, referred to as “being in the zone,” is where intelligent spontaneity and effortless action flourish via a practice rooted in permitting the natural harmony of the cosmos to prevail. 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.

A guide to uncovering the enlightenment already within us • Builds on Buddhist, Hindu, and Taoist wisdom to express the timeless and ever-present nature of enlightenment • Reveals the negative impact of social and cultural conditioning on our psyche and how to counteract this through meditation and reframing our understanding of time • Shows how to uncover the original spontaneous awareness we were born with 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. Building on knowledge from spiritual traditions including Buddhism, Hinduism, and Taoism, Gregory expresses the timeless and ever-present nature of enlightenment. He illustrates how rigid practices and initiations can become a form of spiritual postponement, continually putting off our enlightenment because we feel we are doing something good and noble. To chase enlightenment through spiritual practice is to assume it is a quality bound to time. The author helps us see that we are already what we are seeking--once we understand that existing in this world is itself a miracle beyond words, then the magic and beauty of our world will unfold. In the same way we remember someone’s name without thinking about it, we also remember that we are enlightened when we stop searching for the experience. Emerging from the Middle Way of the Buddha, Lao-tzu’s Way of the Tao, Yoga, the Great Work of Gnosticism, the Hermetic Art of Alchemy, and quantum physics, Gregory presents a way to the state of consciousness--enlightenment, nirvana, or samadhi--in which eternity and time are one. He shows us how to counteract the negative impact of social and cultural conditioning on our psyche through meditation and reframing our understanding of time. The author explains how meditation in its truest form takes our awareness of nowness from theory to practice. Guiding us away from a time-bound understanding of enlightenment, Gregory shows us how to find ourselves in the stillness of now where the peace you are is the peace you give to the world.
