Religion is a structured institution with hierarchy and a set of guide-lines in the form of dogma. Most religions believe in a god or gods which they worship through various rituals. When one is a member of a particular religion then they would have obligations to fulfil as part of that community.
Spirituality is available to all humans’ regards of religion. Religious people can be both spiritual and religious. Spiritual people need not be religious, but follow their heart from a soul level.
Some of us might need the discipline and commitment of a supporting community through a religion. The rest of us though find inner peace through our unique connection to the universal freedom of spirituality.
