I taught my children a simple definition: Religion is human-made; spirtuality is from God.
More precisely, religion is the human interpretation of things not cpable of being known or completely understood in this existence. No wonder why there is so much division and untold alternative views.
Spirituality is that essence of ourselves and all we experience within our existence, that does not need to be perceived, rationalized nor justified. Let go of pride and continue to learn and absorb in your humbleness.
