The negative thoughts and feelings that are inflicted upon us might also come from inside of us too. While honest self-reflection is healthy and can lead to positive change, it's also important to be kind to ourselves and remember the things we do well. 

To be able to recognize and separate from destructive voices, we must first recognize that many thoughts we regard as our own point of view may not really be representative of our true self.

Most people have never been treated as poorly by another human being as they have by the voices in their own heads. So what are we to do with this voice? What's this voice for?

As my friend so wisely pointed out, who was I to judge what was excellence in my yoga practice? My ego, the judge, was arrogant enough to think it knew better than my body what was right and good for me.

The only thing you need do is find security within yourself -- to reach the point where what you think of yourself becomes more important than any external opinion.
