Contemplating the cessation of suffering (the third noble truth) relates to the first two contemplations. When you know suffering and its causes, then you can end suffering. Knowing that suffering and its accumulation arise from causes and conditions means realizing the impermanence and empty nature of suffering. For example, if you realize that money and thoughts relating to it are dependent on causes and conditions, then having it, not having it, working hard for it, or losing it , will not cause suffering. There is no reason to get attached to it. If you are successful in this contemplation, suffering will cease.
Contemplating cessation (the fourth noble truth) is difficult because there is no concrete object of contemplation. It is, therefore, essential to contemplate the path that leads to the cessation of suffering. Contemplating the path means that you persist on the practice path in accordance with the three studies of precepts, concentration, and wisdom. There are people who think of themselves as great practitioners. They point to the number of years they have practiced and the experiences they have had. However, if their practice is not in accordance with these three studies, it cannot be considered Buddhist practice.
Unless you are fully enlightened, suffering its cause, its cessation, and the path still exist for you. Only when you experience genuine wisdom do the four noble truths reveal themselves as being empty and illusory. That is wisdom without outflows.
