Worldly shapes are deceptive:

Friends! If you pass beyond these deceiving forms
You can see rose gardens behind other rose gardens
When you break up and burn off your own form
You have learnt to surrender to the universal form.
(M III / 578-579)

Kill these four birds:
Cut off these four living birds' heads
Make them immortal and save them from dust
They are duck of greed, peacock of show
Crow of desires and cock of lust
They are four elements living in people's heads.
(M V / 42-43)
