Spirituality from a secular worldview is a fruitful, elevated quality of a person, aimed at higher humanistic values and the ennoblement of social life.
The key value of spirituality is its focus on making life more humane, creation of a reliable future for everyone, and Human's ascension to a more sophisticated state.
Homo sapiens made a significant leap in spiritual development when conscious benevolence emerged during its evolutionary history. Today, humanity has the capacity to profoundly advance its humaneness, rationality, and culture, transforming itself into a fundamentally new species — Homo Sublimis, the Sublime Human — provided it recognizes the importance of this transformation and consciously strives toward elevated and noble ideals.
Homo sapiens will become a spiritual being when a stable predominance of the appropriate combined attributes is present within them: humanity, rationality, a love for the beautiful, and an orientation towards the distant future.
A relevant life stance is an energetic dedication to a fulfilling life and the fulfillment of duty in the name of raising Humanity onto the pedestal of humaneness.
While Homo sapiens may not be saintly, they're pretty decent. We have what we have. Most importantly, there's a great chance to nurture and create a new kind of human — Homo humanus, the Humane Human.
