One of my biggest issues with modern organized religion is the lack of willingness to hear other sides of an argument.
For this reason any many more, I always tell people: Whatever it is you need to do to keep from being a jerk to your fellow man or shooting up a school or anything like that DO IT. Most of it is not for me, but a lot of it i can vibe with, doing good things for others, being selfless, all that good stuff. It makes you feel good. So in that case, yeah do that shyt. As far as the the nature of all things? If you got the answers homie, lay it on us, but I don't and I don't pretend to. I'm just giving you my POV. It is by no means the rule of thumb or the grand answer.
Hell some people meditate and all they do is feel relaxed. That's why you never tell anyone what to feel per se because they'll be searching for shyt that's either not there or not for them. But the benefits will still be there, lower blood pressure, better mental health and better aspects of physical well being as per the article in the OP.
