Emotion arises at the place where mind and body meet. It is the body's reaction to your mind — or you might say, a reflection of your mind in the body.

You may not yet be able to bring your unconscious mind activity into awareness as thoughts, but it will always be reflected in the body as an emotion, and of this you can become aware.

Inherent in the impulse to be free, is insecurity. The impulse to be free comes from outside of the mind, and because of this, it makes the mind feel very insecure. Most spiritual seekers move away from this insecurity by seeking and striving for a distant spiritual goal. That’s how they avoid feeling insecure.
Spiritual people can be some of the most violent people you will ever meet. Mostly, they are violent to themselves. They violently try to control their minds, their emotions, and their bodies. They become upset with themselves and beat themselves up for not rising up to the conditioned mind's idea of what it believes enlightenment to be. No one ever became free through such violence. Why is it that so few people are truly free? Because they try to conform to ideas, concepts, and beliefs in their heads. They try to concentrate their way to heaven. But freedom is about the natural state, the spontaneous and un-self-conscious expression of beingness. If you want to find it, see that the very idea of "a someone who is in control" is a concept created by the mind. Take one step backward into the unknown.
To achieve that state of lasting happiness and absolute peace, we must first know how to calm the mind, to concentrate and go beyond the mind. By turning the mind's concentration inward, upon the self, we can deepen that experience of perfect concentration. This is the state of Meditation.
The mental ability to concentrate is inherent to all; it is not extraordinary or mysterious. Meditation is not something that a Yogi has to teach you; you already have the ability to shut out thoughts.
