This Sunday is Easter, typically the most joyous day of the church year for Christians. People in my spiritual tradition gather even when they don't typically attend church.
Sometimes they sport new clothing, hats, or suits. The mood is festive. In our part of the world Easter is also associated with the end of winter.
Flowers abound, trumpets join with organs and choirs and the word Alleluia is repeated in the hymns and anthems, all of which celebrate new life, the power of resurrection.
