The second chakra is the chakra of creativity, pure attention and pure knowledge.
It is the one which connects us to the inner source of inspiration, and enables us to experience the beauty around us.
The pure knowledge given by this chakra is not mental, but it is direct perception of the Reality, that can be felt in our palms and indicates our subtle blockages.
Also this is the center of pure, steady attention and power of concentration.
On the physical level it looks after our liver, kidneys, and the lower abdomen.
When we think too much, this center gets drained of energy and diseases like diabetes or blood cancer can occur when this chakra goes completely out of balance.
