Loving-kindness and compassion are critical elements of the path, but they can lead to fatigue and even burnout if left unchecked. In order to prevent this from happening, we must infuse them with wisdom. By doing so, our loving-kindness and compassion will grow in strength and be more sustainable. The result of this process is what Mingyur Rinpoche refers to as nonconceptual loving-kindness and compassion, a state of mind that is free from bias and distinction and is open to all beings. As described in this video, the process of infusing loving-kindness and compassion with wisdom requires us to investigate the self.
