In order to even enter this discussion, I would need a definition of terms, or we will be debating in circles.

Religion is following a dogma. Spirituality is a by-product of activities such as meditation and music.

IMHO, I think "spiritual" is generally just a euphemism for "I'm not an atheist."

There is no correlation between the two. Religion is about praxis and doctrine. Spirituality refers to inner conviction.

As far as I can tell, the thing about both is a belief in what can't be proven, and works totally on the imagination.

Absofuckinglutly religion is a cult and spiritualism is an individual thing

It all depends on definitions.

In my view, religion is just organized spirituality, and someone who disavows religion is just a religion of one (at best).

Religious faith is a failed epistemology no matter who does or doesn't practice it with you.

I believe they can be very different, and they can be mutually inclusive. Spirituality can mean different things to different folks. Religious means you follow a religious doctrine created by a religious organization, and that is where the trouble starts. At least that is the way I see it.

It depends on word usages and definitions. As a Religious Naturalist I am both religious and spiritual. There are different ways of being religious. To be spiritual is to feel deep awe and reverence for reality and to face existence without shirking. That’s my definition.

I've had people tell me that I am "spiritual" but this can mean anything that you want it to mean. Usually it is a copout for believing in your own way. This means religion and spiritual are concurrent.

Spirituality is about one’s soul and inner self. Being spiritual involves holding one’s personal set of beliefs and practices and searching for ones purpose in life. Spirituality is broader and more abstract than religion. Religion maintains a defined tangible code of ethics, while spirituality is largely undefinable

I do not use the word "spiritual, as I do not believe that human beings have pirits. We are moral, aesthetic, thinking, and deeply feeling beings, yes. But, I do not call that spiritual.

Hiking is a transcendent, uplifting and spiritual experience for me. I have been an atheist since age 13.

Since age 21, I have hiked over 200 miles/year with over 50,000' of elevation gain. It's awe-inspiring. I feel grounded and centered high in the mountains.

I think being spiritual is being emotional, and being religious is practicing emotional discipline.
