According to Henepola Gunaratana in "Beyond Mindfulness in Plain English", hatred is often the final obstacle that needs to be overcome in one's mind. Once this negativity is removed, a natural sense of metta, or loving-kindness, emerges. This transformation fills the mental void with positive feelings towards all beings, suggesting that the absence of aversion fosters connection and warmth.
As one lets go of their tendency to reject or distance themselves from others, they inevitably cultivate a sense of closeness and friendliness. This shift in perspective leads to the realization that everyone can be perceived as a friend, promoting an atmosphere of positivity and acceptance in interpersonal relationships.
