A haiku (Japanese) is a poem that includes a first line of five syllables, a second line of seven syllables, and a third line of five syllables. The challenge is to say something worth saying in seventeen syllables.
Now, Metta, Silence (five syllables) (steps 1-3)
Body, Feelings, Mind, Objects (seven syllables) (Steps 4-7)
Doctrine, Koans, Teach (five syllables) (steps 8-10)
These 17 syllables summarize the ten steps of this course and make them easy to remember.
