Regret arises with a tag saying feelings of remorse belong to us and must be endured. This is a lie. Forgiveness belongs to us as much as to those we choose to bestow it upon. Situations are best evaluated after dining and resting.
Pray to keep your mind where it belongs.
Read scripture, it brightens the white lines on the edges of your road.
Meditate. Listen only to your breath.
Warriors of Light are not perfect in their steps but they are willing to learn the new dances. Always looking up they see the Light and greased with willingness it can reach and soothe all parts of their soul.
