Brahmavihara Meditation
Ven. Analayo is a scholar-monk ordained in the Sri Lankan tradition. In this video, he shows that metta (loving-kindness) is just 1 out of 4 states of a loving mind-heart. He teaches a method of radiating the brahmavihara in all directions in accordance to the early suttas unlike the more common version of metta meditation that radiates metta in succeeding waves to different groups or classes of beings.
