“Spirituality” is a slippery term and difficult to define. It could refer to the human non-material soul, or inner states or dispositions, religious devotion or piety, spiritual disciplines like prayers, fasting, meditation, solitude, etc.
Generally speaking, “spirituality” refers to human connection and interaction with the transcendence, the divine, or the spirit world.
In 2018 Yale and Columbia scientists found the spiritual part of the human brain which they called the neurobiological home of spirituality.
This deep yearning and thirst for connecting with the transcendence or the spirit world is reflected in bookstores under categories such as “Spirituality,” “Mind, Body, Soul,” “Religions,” “Self-Help,” “Discover Personality Type,” “Reincarnation,” “Mysticism,” “Yoga and Meditation Practices,” etc.
But all these are really nothing new: we learn that humankind is made in the image of God from the creation story in Gen. 1-2. There is an in-born desire and ability for every person to relate beyond self, to others, to the whole cosmos, and ultimately to God.
