The poet Gary Snyder says, "The truly affluent are those who do not need anything." That observation does not refer to your material wealth, but speaks about the condition of your heart.
Though many Sufi saints have owned little or no property, this was a matter of choice, not of necessity. True wealth is a state in which you do not crave anything that you do not already have.
What the Sufis mean by "poverty" is lack of attachment to anything but air, food, and sleep. A heart that is full of the things of this world has no place for God. An empty heart has space to long for God to fill it.— James Fadiman, Robert Frager, Essential Sufism by James Fadiman, editor, Robert Frager, editor
