Ageing and Oldness
This state remains in the body for a long time, until the body is worn out by aging. In that state, the body’s machine will no longer have the previous strength and cannot correctly exploit celestial gases and external atoms to carry out the same actions. In other words, the lungs that were once capable of properly carrying out respiration will no longer have that initial capability.
The consumed small atoms that used to be robust and continuously purified the blood, now no longer have that initial power and lack that necessary force and strength to circulate blood. All these factors cause deficiencies in the body.
So accordingly, we say that one has become old. These older people become more silent than before and no longer hold the same power, pressure, pace, and circulation, just like a wheel that becomes worn out after time.
