Religion is established by man for various and specific reasons.
Spirituality is found within ourselves. It is what you believe in and have faith with, in positive aspects.
This is their differences:
Religion is inferred to a belief.
Spiritual lets you experience the Divine consciousness.
Religion is sometimes forced.
Spiritual lets you choose what you want to believe.
Religion focuses more in our sins and guilt.
Spiritual lets you focuses more on how we forgive ourselves and how we deal with it.
Religion is to believe in one God.
Spiritual lets you meditate in ourselves.
Religion offers religious activities or rituals.
Spiritual encourages you to reach Spiritual ascent.
Religion is sometimes based on one's invent and imagination.
Spiritual lets you discover more.
Religion is an outer worship.
Spiritual is an inner worship.
For me, spirituality is more important than religion.
Those are just my conclusion and opinions and based on my research.
The reason why I posted this is because people sometimes misunderstand the concept about Religion and Spirituality.
