Spirituality means different things to different people.
Here are some descriptions that I find meaningful:
"...spirituality is not a separate part of life but rather the deepest dimension and ground of all life."
[from the Institute of Spiritual Companionship]
"Spirituality has many definitions but at its core spirituality helps to give our life context. It's not necessarily connected to a specific belief system or even religious worship. Instead, it arises from your connection with yourself and with others, the development of your personal value system, and your search for meaning in life...Spirituality is different for everyone."
[from Mayo Clinic's website on "Stress Management"]
"The essence of the spiritual life is to stay connected to the sacred place within that holds the memory of wholeness, peace and balance for us, no matter how far our hearts or minds may be pulled."
[Jonathan H. Ellerby]
To me, my spirituality is what motivates me, deep down, to get out of bed in the morning and face the adventure of a new day; and then my spirituality helps me cope with whatever joys and sorrows may come.
