The "Voice In Our Head"

The mind is a wonderful tool for thinking, but it has a dark side. There is an aspect of the mind that is not useful but pretends to be useful, which is called the egoic mind. It is the aspect of our mind that chats with us as we move about our day. It is the "voice in our head," as Eckhart Tolle calls it.
Not only do we believe these thoughts, but we believe they are "ours." We identify with them—we feel they reflect who we are. We don't tend to question our own thoughts, although we readily question other people's thoughts, especially if those thoughts are different from ours.

 But when we stop and examine what this mental voice is saying, we discover a lot of contradictory advice, misinformation, prejudices, judgments, and other negativity. This mental voice is often unkind, belittling, fearful, self-doubting, judgmental, complaining, confused, and unhelpful.
It turns out that the voice in our head is not a very good guide to life, and yet we tend to accept what it says and do what it suggests. This voice, in fact, is the cause of human suffering. It fights life, rails against it, and is discontent and afraid. It is the voice of the false self—the ego—not the true self.
The thoughts that arise in our mind cause every negative emotion we experience: fear, guilt, anger, jealousy, shame, sadness, resentment, envy, hopelessness, worthlessness, and depression.
Without these thoughts, we would live in peace within ourselves and in harmony with others.
