Is the soul eternal

[tackattack]

Restated: Assuming the soul exists (I know it's a big leap for some), Would the soul be eternal or temporary? eternal is self defining and we'll define soul as any of the following or your own definition :
1. the principle of life, feeling, thought, and action in humans, regarded as a distinct entity separate from the body, and commonly held to be separable in existence from the body; the spiritual part of humans as distinct from the physical part.
2. the spiritual part of humans regarded in its moral aspect, or as believed to survive death and be subject to happiness or misery in a life to come: arguing the immortality of the soul.
3. the disembodied spirit of a deceased person: He feared the soul of the deceased would haunt him.
4. The part of self that is intangible or spiritual and distinct from the brain and mind or any intellecual, feeling or willing aspects thereof.
