You choose every minute and every day to focus on what you will. Sadness, fear, hate, anger - all heavy emotions that make your already dense body heavier. What purpose do they serve, ask yourself that question.
Would you put your human hand in a flame and then explain that it is impossible to avoid...the flame is here and it just must be experienced. Nonsense. You removed your hand for your own personal protection. Why do you not do the same with negative emotions?
You have the same opportunity to remove your spirit, mind, thoughts from the negative flame as you do to remove your physical hand. Develop the muscle of choice and the attitude of choice. Do not wallow or seek more flames to experience. Seek out what makes you happy for that is why you came. Blessings.
