To accomplish this, here is a very effective writing exercise:
"In a quiet place, light a white candle and set a timer for 12 minutes. With pen in hand, begin to write stream-of-consciousness style about any unresolved issue with which you’ve not been honest with yourself or others. Let the emotions move you and don’t worry about making your writing legible. At the end of 12 minutes, stop. Don’t read what you’ve written! You’ve purged this negative energy and don’t want to take it back into your consciousness. Crunch the paper up and, in a safe place like a patio or barbeque grill, burn it. Fire is transformative and cleansing because it changes the chemical composition of things. Do this as often as needed to transmute the negative energy from similar situations."
"Why 12 minutes? It’s because 12 has great spiritual significance across nearly all belief systems. Most importantly, it symbolizes balance as there are 12 hours of day and night in each 24-hour period. There are also 12 months in a year, symbolizing the end of a cycle and renewal."
