Chains of the Spirit

From publisher blurb: Some ghosts spend their afterlife in quiet meditation instead of mischief and malevolence. They study spirituality from a unique perspective, pursuing a deeper understanding of their own nature and a heightened awareness of the cosmos around them. Chains of the Spirit provides nineteen new feats specifically designed for such ghosts; those who desire to transcend their remaining ties to the material world, expand their conscious minds, and seek enlightenment.
