Chakras can be blocked by certain emotions.If there is an imbalance in a chakra these emotions will be evident in the :
Root Chakra - feelings affecting basic needs (money, shelter and food)
Sacral Chakra - lack of commitment in relationships, lack of ability to express emotions, lacking in having fun, being creative, issues around sexuality
Solar Plexus - issues of personal power and self esteem, self critical, fears rejection, criticism and physical appearance
Heart Chakra - over loving, jealousy, abandonment, anger, bitterness, fear of loneliness
Third Eye Chakra - moodiness, volatility, daydream , exaggerates imagination
Crown Chakra - issues with self knowledge and greater power, rigid thoughts on religion and spirituality, constant confusion, prejudice and fear of alienation
There may be more than one chakra that is imbalanced or blocked . This happens when other chakras try top compensate for a blocked chakra and others become either overactive or underactive. The best way to start balancing them is to start at the Root Chakra and work your way up to the Crown Chakra.
