[Nothatspecial]

The sole lecture of the Four Noble Truths awakes toward the understanding of suffering. There is no need to believe because once you have read carefully that core teaching this awakening is in itself the arising of Right View. This is what in Soto is meant by Luminous Mind or Buddha Nature. It is an experience. It is a deep insight. You will never see the world again in the same way you saw it before the knowledge of this simple (but no easy) teaching.

MN141 is clear about this: "What is right understanding? It is this knowledge of suffering, knowledge of the arising of suffering, knowledge of the cessation of suffering, knowledge of the path leading to the cessation of suffering — this is called right understanding".

Also MN9 develops in more detail Samma ditthi or Right View exploring other ways to understand dukkha and its cessation but remembering again that Right View is about understanding the Four Noble Truths:

"The Four Noble Truths
13. Saying, "Good, friend," the bhikkhus delighted and rejoiced in the Venerable Sariputta's words. Then they asked him a further question: "But, friend, might there be another way in which a noble disciple is one of right view... and has arrived at this true Dhamma?" — "There might be, friends.

14. "When, friends, a noble disciple understands suffering, the origin of suffering, the cessation of suffering, and the way leading to the cessation of suffering, in that way he is one of right view... and has arrived at this true Dhamma.

15. "And what is suffering, what is the origin of suffering, what is the cessation of suffering, what is the way leading to the cessation of suffering? Birth is suffering; aging is suffering; sickness is suffering; death is suffering; sorrow, lamentation, pain, grief and despair are suffering; not to obtain what one wants is suffering; in short, the five aggregates affected by clinging are suffering. This is called suffering.

16. "And what is the origin of suffering? It is craving, which brings renewal of being, is accompanied by delight and lust, and delights in this and that; that is, craving for sensual pleasures, craving for being and craving for non-being. This is called the origin of suffering.

17. "And what is the cessation of suffering? It is the remainderless fading away and ceasing, the giving up, relinquishing, letting go and rejecting of that same craving. This is called the cessation of suffering.

18. "And what is the way leading to the cessation of suffering? It is just this Noble Eightfold Path; that is, right view... right concentration. This is called the way leading to the cessation of suffering.

19. "When a noble disciple has thus understood suffering, the origin of suffering, the cessation of suffering, and the way leading to the cessation of suffering... he here and now makes an end of suffering. In that way too a noble disciple is one of right view... and has arrived at this true Dhamma."

Soto has a deep concern about this development through what we call sitting meditation or zazen.
