The conditions shaping us do not all come from outside. We also live inside the conditions of our own bodies.
The same situation can be experienced differently depending on whether you are rested or exhausted, nourished or hungry, comfortable or in pain. What seems manageable at one time can feel overwhelming at another, even when nothing outside you has changed.
This is not separate from how the system organizes. Bodily state is part of the information the system is organizing around.
Fatigue can narrow attention and reduce patience. Pain can make demands feel larger. Hunger can change mood and concentration. Poor sleep can make uncertainty harder to tolerate. Illness can reduce what is available for everything else.
The reverse is also true. Strength, nourishment, rest, physical ease, and recovery can change what is available. The external situation may be exactly the same, while the person meeting it is not.
This is why dividing experience into “physical” and “psychological” can become misleading. Thoughts, emotions, perception, attention, movement, energy, and bodily state continually affect one another because they belong to the same living system.
The body is not simply where psychological problems eventually show up. It is part of the conditions from which we perceive, respond, and live.
