Fear

There is an amount of fear associated with all our emotions. Whatever we may experience, we seem to be experiencing it with a sense of fear attached to it.  Be it happiness, where we fear that it won't last, or sadness, where we are afraid that it will consume us and cause us pain. It is the fear that causes the pain in us.  When we are afraid, we are uncertain and when we are uncertain, we are insecure. When we are insecure, we undertake attempts to move towards security, frantically searching all around us, instead of looking within us. For, this security actually lies within. If we accept the emotion as it is and allow ourselves to feel it, without fearing it, we will find that it will pass and a new emotion takes over. But if each of our emotions are associated with fear- fear that it is short lived, fear that it is eternal, fear that makes us inferior, as in the case of jealousy, fear that we will not be treated justly, as in the case of anger, and the fear of fear itself- we live in a constant state of fear. Instead, we must embrace the emotion without being afraid of it. Happiness is a light feeling that brings hope, sadness is a heavy feeling that slows you down, makes you reconsider life and helps you grow, anger is an intense feeling that reflects what you are passionate about, and jealousy is a churning feeling that reflects to you your strengths and weaknesses,while fear prepares you for action.  
Hence, these emotions must be felt in their entirety without fearing them. It is not to say that each of these emotions are mutually exclusive, and that they include only the feelings mentioned here. Instead, it means that we must accept all our emotions as they are, and as we feel them, and not fear them. If you feel afraid, then be afraid. But do not be afraid that you are afraid. If you are happy, be happy. Do not wonder when you will be sad again. If you are sad, do not lose hope that you can never be okay again. If you are angry, count to ten and release your anger.  Do not be afraid that you will be judged for showing your anger and branded as a harsh person. If you are jealous, accept that your own insecurities are making you feel this way, and reflect on who you are. Do not fear an emotion that's on its way. Welcome it with open arms, be a good host, and hug it on its way out, knowing that you will see it again, and when you do, it will no longer be an acquaintance, but an old friend.
