When you become a witness to your own thoughts, you begin to be more humble. You may consider whether others' thoughts are as valuable. You may even consider what others say as a potential source of life changing wisdom. A person with the habit of examining themselves loses the need to defend what they have done. A meditator need not keep asking others for approval.
Meditation gives comfort.
It puts us in touch with inner knowledge. In this way we need not live as much for what others think of us. We live more for what we ourselves decide we would like to be. This is a healthy way to live. It enhances the work of the immune system and shifts people away from reliance on adrenaline.
