I do not perceive even one other thing, O monks, that when undeveloped and uncultivated entails such great suffering as the mind. The mind when undeveloped and uncultivated entails great suffering.
Nirvana is this moment seen directly. There is no where else than here. The only gate is now. The only doorway is your own body and mind. There’s nowhere to go. There’s nothing else to be. There’s no destination. It’s not something to aim for in the afterlife. It’s simply the quality of this moment.
Ideally, when Christians meet, as Christians do, to take counsel together, their purpose is not ( or should not be) to ascertain what is the mind of the majority but what is the mind of the Holy Spirit - something which may be quite different.
