It is commonly considered rude to keep silent in the company of others, but voluntary silence connects rather than distances us from others whose individual differences temporarily fade away creating a shared feeling of harmony and oneness.
Gardening can provide an opportunity to slow down, be still, breathe, and connect with another form of life. For me, it is an experience of communion; I become one with this precious life in my garden, and it heightens my experience of love in the world. And that is what spirituality is all about: growing in love.
