Thanks Xanthippe. I avoid use of the word due to its religious, supernatural connotation, but Harris and others appear to be making its more secular definition relevant. That's probably a good thing. Words have a way of evolving to mean whatever society wants them to mean. I try not to get too hung up on word meanings because they change. Thanks for citing what I was referencing!! You made it much clearer.
To illustrate the blissful experience. This past weekend my GF and I hiked one of the most beautiful trails in the US. The lower elevations were lush forests with streams, bridges, ferns, etc., while the higher elevations were cooler, drier, rockier, with less vegetation but amazing views. Spiritual. Plus I got to follow her up the trail and view her amazing rear end for several hours. Blissful.
However, on the way back down the mountain my GF had to use the bathroom. Very badly. If it were me I would have found the closest rhododendron thicket (that and no cellulite are probably our gender's only advantages), but being a girl she held out as long as she could until, about 1/2 mile from the trailhead, she darted to the bathrooms. I'm quite certain that she would tell you the spiritual moment ended as soon as the immediate bodily need arrived. That's my point made on p. 2 of this OP.
Again, thanks Xanthippe.
