Dervish / Darvesh: Book 1 of Rumi's Masnavi

Water that's poured inside will sink the boat

While water underneath keeps it afloat.

Driving wealth from his heart to keep it pure

King Solomon preferred the title 'Poor':

That sealed jar in the stormy sea out there

Floats on the waves because it's full of air,

When you've the air of dervishood inside

You'll float above the world and there abide...
