I find the Buddha's metaphor for emptiness extremely helpful. In the Phena Sutta, the Buddha compares the aggregates to foam in a river, bubbles in water, a mirage, and other illusory, impermanent phenomena. They are all empty, he asserts: "However you observe them, appropriately examine them, they're empty, void to whoever sees them appropriately" (SN 22.95).
