A definition is just a definition, being spiritual does not involve a "way", no way that is distinguished from any other way that is.
I'd have to say the same thing for views. If we are interested in the truth, and you already know you've got "a view", then why would you be concerned with that view? You just have to take a step back to that which knows it is only your personal view, that is closer to the truth.
Actually, I don't think thought is required. You can have a person that's amicable and gets along with all people regardless of spiritual orientation or lack of it, and that is what I would call a spiritual person. (as long as they don't do it out of propriety and PC BS) In fact, learning of certain spiritual ideas will more likely mess that up. Even if we're talking about people who've never been involved in a group like the JWs, they could very well miss that which is real in their effort to become spiritual according to their beliefs, even if those beliefs are very reasonable, they're only beliefs.
