We know only that we are living in these bodies and have a vague idea, because we have heard it, and because our faith tells us so, that we possess souls. As to what good qualities there may be in our souls, or who dwells within them, or how precious they are, those are things which seldom consider and so we trouble little about carefully preserving the soul's beauty.
Teresa of AvilaWhile the soul is in mortal sin, nothing can profit it; none of its good works merit an eternal reward, since they do not proceed from God as their first principle, and by Him alone is our virtue real virtue.
Teresa of Avila
