Outdoors. Pretty much anywhere not constricted by four walls and snuffed by a ceiling, not supplied with mechanical air.
The sun. The breeze. The rain. The moon and stars. Earth. Sand. Water. Snow. Trees in all their seasonal finery. Flowers, grasses, brambles and bracken. Animals, from the tiniest beetle to the greatest whale.
And my personal altar in that boundless sanctuary—my garden.
The kiss of the sun for pardon,
The song of the birds for mirth,
One is nearer God's heart in a garden
Than anywhere else on earth.
