I am more religious. I believe in a God and pray from a selection of prayers I'd learnt when young.
The spiritual side comes from believing in a God, the Holy Spirit and angels and hence why I've always associated the spiritual with religion when I see some practicing a spiritual life through using karmas and meditation in their lives.
Yet religious practices use prayers in a meditative form which helps the person to relax.
In some ways, I'd like to develop my spiritual side more but I always revert to religious beliefs and practices in my daily life and I've got to say, it really helps me throughout the day.
