Religion derives from spirituality. Spirituality can be the ambition to develop as a person, find answers to existential questions or just find comfort within yourself and around yourself. Anyone can be spiritual, even atheists. Religion on the other hand tends to be more organised and structured to a set of predetermined rules or guidelines. Religion also often involves some kind of belief in a holy entity, place or object. Buddhism, which do not talk much of this kind of belief, might be the exception to this, but most would say it's more of a philosophy than religion. A religion also has to have a certain number of followers for it to be called a religion, which makes it more of a collective and social thing than what spirituality can be. You can be spiritual in the exact same way as someone who is religious, but you can also stay spiritual as an individual, without the conformity from others.
