Prayer for an attractive woman. This prayer is meant to be a positive habit you can establish for the cue of seeing an attractive woman in order to replace other responses that are lacking in love.
I recommend starting with just the first part to keep it easy: “Come Holy Spirit, kindle in her the fire of your love.” This is an excellent all-purpose prayer for anyone and can train you to desire something good for her. I not aware of any deeper good than being kindled with love for God, so truly this is asking for her highest good.
When you are able, add in the second line: “grant me the grace of chastity”. Now you are not only asking for something good for her, but asking for grace from God to love her and all people with a rich and pure, seeing yourself and her as whole people (not just minds or bodies or other parts of people) and growing in desire to have loving, healthy, integrated relationships, not lustful, fragmented, adversarial, or exploitative relationships.
The last part of the prayer is meant to help imagine the loving, chaste, healthy potential you and kindle you with desire for it. You could modify this part as God gives you vision for the beautiful and healthy state he is calling you into.
