Your good deeds are like small seeds that grow and proliferate goodness.
So it makes sense that spreading actual seeds (that sprout into something beautiful) is a good deed!
Why not buy a few packets of wildflower seeds, put them in your pocket, then sow them freely?
Scatter color and beauty in random, surprising places. In a vacant lot. On a hillside. Along a bike path. Along the shoulder of a highway. Along a barren sidewalk.
Just imagine the pleasure and joy they will produce!
Seeds are miracles. Spread wildflower seeds, and countless others will be surprised by miracles.
