Try to do everything with a feeling of joy and elevated spirituality. When we act in a joyful way our brain secretes serotonin and endorphins that make us feel good.
There are four synonyms for Joy in Hebrew: chedva, gila, simcha and sason. We often mention these words together in our songs and prayers. All four aspects or levels come together to create the experience of Joy.
