IMO, one can learn quite a few things from it, like i.e.:
- patience (Jonas)
- gentleness (Jonas)
- forgiveness (Jonas)
- courage (Sidonie)
I've read Scarlett Scott's Scoundrel series with titles such as "Duke of Debauchery", "Duke of Depravity", etc. The covers are less cheesy, but still cheesy enough.
The series were intense at every level. By the third book (my favorite of that series), I really got a very strong sense of the gifts of the spirit - love, joy, patience, gentleness, etc. and how love never fails, despite the odds. It felt like I was like tapping from within into the new reality that Paul spoke about.
"By contrast, the fruit of the Spirit is love, joy, peace, patience, kindness, generosity, faithfulness, gentleness, and self-control." (Gal 5:22f)
13 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. 2 If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. 3 If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
4 Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres.
8 Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. 9 For we know in part and we prophesy in part, 10 but when completeness comes, what is in part disappears. 11 When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put the ways of childhood behind me. 12 For now we see only a reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known.
13 And now these three remain: faith, hope and love. But the greatest of these is love. (1 Corinthians 13)
The stories cover universal themes of war, slavery, etc. that are fairly common during past life recollections. So even though some stories could stir up quite a bit at every level, I found them all very healing and joyful.
