One can live without Religion but not without Spirituality for Spirituality forms the core of very existence of every living being. It is the spirit within every human being that we exist as a physical form on Mother Earth. We may or may not indulge in understanding Spirituality or a Religion but inherently every living being pursues the path of Spirituality in every manifestation. Spirituality is that fundamental of life which cannot be ignored by one.
Religion is an institution established by man for various reasons. Exert control, instill morality, stroke egos, or whatever it does. Organized, structured religions all but remove god from the equation. You confess your sins to a clergy member, go to elaborate churches to worship, told what to pray and when to pray it. All those factors remove you from god.
Spirituality is born in a person and develops in the person. It may be kick started by a religion, or it may be kick started by a revelation. Spirituality extends to all facets of a person’s life. Spirituality is chosen while religion is often times forced.
