Try This Spiritual Exercise!
Creating Happiness
In your spiritual exercise, imagine standing in front of a big glass window. Next to you is a bucket with cleaning supplies: a rag, a squeegee, and a spray bottle of window cleaner. Spend some time cleaning this window until the Light of ECK pours through it like a ray of sunshine.
Anytime you feel yourself less happy than you want to be, spend some time cleaning your inner window so that more Light can shine through.
