Is there a line of thought in Buddhism that is less centered on suffering?
The scripture MN 117 explains there are two sorts of Right View or two sorts of Buddha's teaching, namely: (i) supramundane/transcendent; and (ii) mundane/worldly.
The mundane/worldly teachings that focus on avoiding bad kamma, doing good kamma and 'rebirth' are less focused on suffering &amp; the cessation of suffering.
These 'kamma &amp; rebirth' teachings are for the ordinary people called 'puthujjana' who are spiritually blind and naturally unable to discern the unsatisfactoriness and meaninglessness of the world.
These mundane/worldly teachings are to prevent ordinary people inflicting self-harm upon themselves and others.
These mundane/worldly teachings not only include moral teachings but also teachings about generating loving-kindness towards all beings.
