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

Yes, Phena Sutta is one of my favorites ! I like the ending verses:



That is what the Blessed One said. Having said that, the One Well-Gone, the Teacher, said further:

Form is like a glob of foam;
feeling, a bubble;
perception, a mirage;
fabrications, a banana tree;
consciousness, a magic trick —
this has been taught
by the Kinsman of the Sun.
However you observe them,
appropriately examine them,
they're empty, void
to whoever sees them
appropriately.

Beginning with the body
as taught by the One
with profound discernment:
when abandoned by three things
— life, warmth, & consciousness —
form is rejected, cast aside.
When bereft of these
it lies thrown away,
senseless,
a meal for others.
That's the way it goes:
it's a magic trick,
an idiot's babbling.
It's said to be
a murderer.
No substance here
is found.

Thus a monk, persistence aroused,
should view the aggregates
by day & by night,
mindful,
alert;
should discard all fetters;
should make himself
his own refuge;
should live as if
his head were on fire —
in hopes of the state
with no falling away.
