The Sahasrara or crown chakra, the thousand petaled lotus, is the center of illumination and complete wholeness of spiritual enlightenment.  Emotional blockages include indecisiveness and a sense of disconnection or not belonging.  Physical blockages can include headaches, pituitary problems, brain tumors and epilepsy.  Centering this chakra allows you to connect to yourself and the divine universe, free from the interference of ego and a depp understanding that we are all one.
