Our human heart is full of many emotions and old memories. Inside of that heart there is a bright light that is like a candle flame in a room without wind. We can call this our Pure Heart or the Heart of our Divine Self. When we are silent enough we can feel this light and it remains steady and clear. This is what happens sometimes when we meditate. We find this steady and clear presence inside of our self. This is the Pure Heart and the Source of the Universe inside of us.
During the day when we are not in meditation and step out into our life and activity in the world, our heart flame is shaken by the winds of emotion and pressures from the world around us. The Pure Heart is our true self. It is the eye of consciousness that experiences the kind of life we are living. When the eye of the flame is shaking, we cannot see anything clearly. The flickering and shaking of our own vision will distort every perception and we will feel off balance and make mistakes.
