What Is Sam Harris’s Approach to Meditation?
Sam Harris, a neuroscientist, philosopher, and author, Emphasizes the Importance of doing meditation and being mindful. He believes that it benefits of the practice, such as stress reduction, and meaningful insights that can lead to discover about the mind and life.
According to Harris, a key enemy of meditation is being lost in thought, or “thinking without knowing that you’re thinking.”
His method is designed to break this cycle by training attention.
He urges that the meditation is core of understanding about oneself while being stripping out the idea of Religious practice. The main idea is to understand the nature of consciousness and to directly experience the illusion of a fixed “self.”
Through mindfulness, a meditator can observes thoughts as just thoughts and feelings as both of them will arise and pass after a brief moment , without getting lost in them. This practice reveals that the sense of “I” is not a solid entity, but rather a fleeting experience.
Harris’s meditation app, Waking Up, offers a course that guides users through this process. The app includes daily meditations, long guided meditations, and daily “Moments,” which are brief meditations and reminders.
