Thus I have heard:
One time, the Budha was staying at Anaathapindidas Ashrama in Jetavana of Shraavastii.
At that time, Bhagavaan addressed the Bhikshus: “If any one among this assembly harbours such thoughts, I know them all. Though such a person may not speak falsehood openly in the assembly for material gain, I may later observe this person developing clinging thoughts toward possessions, ultimately leading to false speech in the assembly.
Why is this? O Bhikshus!
Attachment to material possessions is extremely hard to abandon! It causes beings to fall into the three woeful realms and prevents attainment of Nirvana!
Therefore, O Bhikshus! If such thoughts have arisen, abandon them immediately. If they have not yet arisen, do not let them take root.
Thus, O Bhikshus, should you train yourselves.”
When the bhikshus heard what the Budha said, they followed it with joy.
