Rabbi Tzvi Hirsch HaCohen of Riminov is quoted in the collection Itturei Torah (Vol. 4, p. 30), saying about this verse:
"Ashes" means a thing of little substance. The word in Hebrew, (deshen), is an acronym for "davar shelo nechshav," something that is not even thought about. This teaches that you should find the sacred in every little thing and raise it up. Anything that seems small and of little value is placed next to the altar. Treat it as a sacred object.
Take time to celebrate the little things of life—the melting of the snow, the laughter of a child, the smile of a friend, your own passing thoughts. Know that each little thing has the sanctity of an offering upon the altar of the Temple, and the holiness of your own deepest prayer.
Everything is holy when we take the time to appreciate it. Every moment is a gateway to the Divine, if we are willing to open ourselves to the moment. Discover your deepest happiness in the appreciation of a world in which even the windblown ashes are an opportunity to connect with the sacred.
