I found this definition interesting.
"Spirituality is a broad concept with room for many perspectives. In general, it includes a sense of connection to something bigger than ourselves, and it typically involves a search for meaning in life. As such, it is a universal human experience—something that touches us all. People may describe a spiritual experience as sacred or transcendent or simply a deep sense of aliveness and interconnectedness.
Some may find that their spiritual life is intricately linked to their association with a church, temple, mosque, or synagogue. Others may pray or find comfort in a personal relationship with God or a higher power. Still others seek meaning through their connections to nature or art. Like your sense of purpose, your personal definition of spirituality may change throughout your life, adapting to your own experiences and relationships."
In other words - a belief in a God is not required.
