The Principle of Mentalism

Everything that exists is a manifestation of a single universal mind or consciousness. This mind is also known as the All, the One, the Source.  Everything that we perceive as physical reality is actually a mental projection of this mind. This principle implies that our own mind is a part of the All and has the same creative power. We can use our mind to shape our reality according to our thoughts and beliefs. Whatever we think and feel becomes our experience. This is why it is so important to be aware of our mental state and choose positive thoughts over negative ones. 

One way to understand this principle is to think of Quantum Physics. Quantum Physics is a branch of science that studies the nature of matter and energy at the smallest level. It has shown that reality is not fixed or objective, but rather depends on the observer and their expectations. For example, light can behave as either a wave or a particle depending on how we measure it. This suggests that reality is not something out there but something in here, in our mind. 

This  show how powerful our mind is and how it can affect our reality.  By applying the principle of mentalism, we can use our mind to create positive outcomes for ourselves and others.
