They all capture our attention, and they cause us to relax and focus. That is when our inner critic, which analyzes information and makes judgments, is quiet and our subconscious mind is open to the power of suggestion. Being receptive to suggestions still does not mean we can be controlled. We each have power over our own thoughts and actions at all times. So often we do not monitor the thoughts we allow to enter our minds.
Thoughts are just another form of energy, food for the mind so to speak.
We can think of our thoughts as seeds and our subconscious mind as a garden. It is very empowering to realize we are each the gardener's of our own garden. We create our own reality at all times simply by what we believe. By monitoring the thoughts we allow to take root and grow in our minds, we can either grow beautiful plants, or we can grow weeds. That is where hypnosis comes in.
