Apparently there is a semantic difference between the term "spiritualism" and "spirituality". The first can be defined as a religious affiliation with a Spiritualist
Church where as the second can't be credibly defined except as a reference to ghosts. The attempts to define "spirituality" are hampered by the fact that not many people agree on what it is and it is entirely scientifically unprovable.

People can offer definitions for "spirituality" but they fall short of meaning since they are subjective experiences that not everyone has. As subjective, they are not testable and are subject to questions of their validity.
