We know the soul is composed of subtle atoms in our body -- and we have the ability to control the movement of those atoms. Most of the things that disturb us are self-generated. Even if somebody smacks you in the face—after the initial pain is gone, all subsequent pain is self-generated by your memory of the smack, which you can control. You can choose to move past it and delight in the fact that your face no longer feels the pain of the smack.
Remember, the gods are eternal because they have a constantly flowing form (like a waterfall). If you smack a waterfall—or even throw a rock at it—it will just move past it.
