When you are in a harmonious environment your mind picks up any excuse to be in conflict. So often small things are enough to create big turmoil. If you have a conflicting environment you tend to seek harmony ... Have you noticed this?
Ask yourself this question: Do you seek harmony in every situation or do you seek to widen the differences and prove your righteousness?
When your survival is at stake, you don't complain that nobody loves you. When you are safe and secure you start demanding attention. Many people create conflict in order to get attention.
The seed of negativity and the tendency for conflict in you can only be annihilated by Sadhana.
