"Pain is inevitable, suffering is optional".

It is the resistance to the pain that is causing the suffering.

If you can successfully work with physical pain, then you are more likely to be able to work with mental pain.

Whether we like it or not, we need to understand and be able to handle suffering to some extent, especially mental suffering, notwithstanding our inclination to acknowledge the fact of suffering or not.

Buddhist teachings stress that life is uncertain, but death is certain; life is precarious but death is sure. Life has death as its goal. There is birth, disease, suffering, old age, and eventually, death. These are all aspects of the process of existence.
