SYMPTOMS
Blockages can manifest as immune system or heart problems, or a lack of compassion. Characteristics of a blocked heart chakra include fear of rejection, feeling unworthy of love or loving too much. If there is blockage in the heart chakra, you may feel unworthy of love and skeptical of anyone who wants to love you (and paranoid that you will wind up hurt, yet again), or your love relationships may be completely co-dependent.

CAUSES
You've probably experienced one or more of the following; shaming, authoritarianism, volatile situations, domination of will, physical abuse, dangerous environment, fear of punishment, enmeshment, age inappropriate responsibilities or inherited shame from parent. If this chakra is imbalanced in some way it means that somewhere along the line, there has been a disruption in your attitude and understanding of love. You may want to give your love with the hopes of gaining control of a person or situation and thus confusing love with manipulation, or you may be giving your love in the hopes of gaining recognition to boost damaged self esteem. You may consequently be a possessive and mistrustful person who lacks much compassion. If the heart chakra is completely blocked, this tends to manifest itself in the antithesis of what the heart represents: you are literally heart-less and quite icy in how you receive yourself and others. If you are not open to love in your life, it is not possible to feel very happy and joyful about life or yourself and, people with blocked heart chakras most certainly do not.

ENERGY FLOW
Look through the characteristics of both excessive and deficient energy flow;

Excessive energy - Spins fast (no harmony)
You may be involved in a co-dependent relationship. You tend to take on the problems of others. The woes of the world affect you too deeply. You have a tendency to smother your children with affection. You give too much and too frequently, often neglecting your own friends. You fall in love too quickly and are easily hurt. You are an air-head- meaning you tend to be forgetful. You have difficulty in sticking to things.

Deficient energy - Spins slow (no harmony)
You feel lonely and isolated - even when you are physically with other people. You have trouble sustaining a healthy, loving relationship or may find it impossible to commit to one. You lack sympathy for others. YOu are bitter and overly critical. You are a passive aggressive. You are selfish and unable to give. It is especially difficult for you to give of yourself. You are miserly with your energy. You feel heavy hearted.
