In the traditional way of life gardens were a ceremonial event for all, an opportunity to give to the Earth as well as to receive. The seeds of good food are also the seeds of good relationship, so caretaking the garden is symbolic of caretaking all beings ... an offering to all.
Whatever we do for the love of God benefits our souls and our lives in a way that ego-motivated actions never can. Whatever we do for the love of God is done with sincerity because it is not motivated by self-interest. We leave our concern for gain and loss, success and failure, in the hands of God. We stop considering ourselves as the sole cause of our actions and their results. Consequently, we become the instruments of a deep wisdom and love.
