Yes actually I posted it because of that one line
How can part of the world leave the world?
It's something I realized while pondering and meditating a long time ago...
The Beatle's song... Dear Prudence, there is a nice line,
"The wind is low, the birds will sing
that you are part of everything..."
Anyway it's pretty. But the idea is that we are part of everything.
Part of everything. Part of the world. Part of the universe. Rumi is saying what I also realized - part of the universe... which has a lifetime of no less than that of the whole universe...
I was happy that I had come up with the same thought as such a brilliant poet as Rumi, although I never could reach his level of poetry.
There is also definitely a parallel between this idea and Nietzsche's idea of Eternal Recurrence.
