How to Practice Loving Kindness Meditation (Metta)
The practice of loving kindness or goodwill meditation is an excellent tool for breaking down barriers as well as restoring humanity and kindness when your mind feels like a battlefield. The benefits are also that you re-train your mind to let go of stress far more easily when the mind is more calm and happy and come up with mutually beneficial solutions to challenges you may be facing.
The relevance of the practice of goodwill meditation is simply that it can tame our emotions and develop the mind to being more humane and more wise.
