This talk explores the traditional benefits and scope of mettā practice, presenting loving-kindness as a force that steadies sleep, brightens the mind, supports concentration, and softens our relationships with human and non-human beings alike. Drawing on classical texts and modern teachers, it emphasizes beginning with what is possible—locating the goodwill already present and gently extending it outward. The practice culminates in the “all beings” category, cultivating an impartial heart free from indifference and ill will.
