Venerable Bhante Vimalaramsi has now created a powerful Forgiveness Meditation. When someone close to you dies and grief, and sometimes even guilt, arise afterwards, one seeks this kind of a meditation to reduce your suffering. This is just one example of unwholesome states that get stuck in your mind.
Additionally Bhante has found that when a student gets stuck in the Metta meditation and is making no progress he suggest the student to go through the Forgiveness Meditation. This enables them to remove the barriers that are there, and as a result, true warm sincere loving-kindness arises. Then the student moves back to the powerful Metta meditation that Bhante teaches. A meditation that will take the student to awakening.
