Consciousness is a term used to describe the awareness of your physical and mental experience. As you might have already realized, not all forms of awareness are the same. There are a number of different states of human consciousness as well as a variety of things that can have an impact on these states of awareness.

Human consciousness is often compared to a stream, constantly changing but always flowing smoothly.

Understanding Consciousness

Have you ever wondered why you feel more energetic in the morning, tried to analyze your dreams, or questioned how hypnosis works? All of these topics are related to human consciousness, which can be altered in a number of different ways (such as performing holotropic breathwork).

Body Clocks

Many people begin the day full of energy but then start to feel run-down by mid-afternoon. Other people struggle to plod through the morning routine only to finally feel energetic in the evening. The daily fluctuations of energy levels are known as the circadian rhythm and play an important role in human consciousness. Sometimes referred to as the body's "clocks," these daily rhythms have a major impact on your consciousness as well as a wide number of physiological states. Understanding these biological and environmental rhythms can tell you a great deal about how body clocks can influence states of consciousness.
