No, not at all. It has to do with the way the individual labels of a
domain name (the parts between the dots) are sent over the wire. It's
part of the DNS at an extremely low level. A lot of people have proposed
a lot of changes to the DNS over many years of its use, and some of
these have been specified and implemented. But an extension of the
length limit isn't something of high importance.

Which most probably is just wrong.

Yes. Please note that overall, there is a limit of 255 ASCII characters,
which includes the dots.
Also, please note that domain names are intended for identification, not
for content (such as poems or prayers or whatever), and that having them
easy to type usually helps.
So the right thing to do is to just choose a short domain name (e.g.
hare-krishna.something) and put the content you are interested in on a
Web page at that address.
That's what everybody else is doing, and it shoudn't have been too
difficult to figure out by yourself without bothering this list (which
has absolutely nothing to do with technical limits on ASCII domain name
