tibetan vajrayana buddhism
Metta Bhavana moves through a fixed sequence — first directing goodwill toward oneself, then a loved one, then a neutral person, then someone difficult, then all beings — using simple repeated phrases ("may you be well, may you be at ease") rather than trying to manufacture a feeling directly. The structured order matters: starting with the hardest person before the heart has warmed up is traditionally considered a common reason people find the practice fails to land.
