One method of overcoming negativity and handling the negative energies is through faith. Do not confuse faith with a mystical or religious concept. Faith is a strength in a human being. If we can recognize faith as a strength and not as something mystical and religious, we will be able to handle the negative energies. Faith will then teach us how to flow and not struggle in life. In the language of philosophy, negation is the outcome of our reaction to something. A rotten piece of flesh is put in front of us. We smell it and we react and that reaction creates a negation of that particular experience. That is known as dwesha, rejection, repulsion. We smell a nice perfume and like it. That liking is also a reaction to that smell. If it is a good thing, we accept and enjoy it. That is known as raga, attraction, attachment. A reaction happens in both of them. One is good, one is bad.
If we live by continuously reacting, life is definitely going to become hell. As human beings, we must have the ability to discriminate between positive and negative reactions. To cling to either one of them will limit and bind the forces of the mind by creating a sense of attachment and not allowing the mind to experience total freedom.
