Two monks and a flag
Two monks were arguing about the temple flag waving in the wind. One said, "The flag moves." The other said, "The wind moves." They argued back and forth but could not agree.
Unable to resolve their disagreement, they approached the abbot, to seek a resolution.
The abbot said, "Monks, it is your minds that are moving! Quit with the papanca monkey chatter and get back to your meditation"
What is the final conviction that comes when radical attention is razor-edge sharp? That the object of the mind is mind-made (manomaya). (Ven. Ñāṇananda)
Having understood name-and-form, which is a product of prolificity,
And which is the root of all malady within and without,
He is released from bondage to the root of all maladies,
That Such-like-one is truly known as 'the one who has understood'. (Snp 3.6)
