Liable to Fall
At Sāvatthī. Seated to one side, Venerable Rādha said to the Buddha: “Sir, they speak of a ‘liability to fall’. What has a liability to fall?” “Rādha, form, feeling, perception, choices, and consciousness have a liability to fall. Seeing this … They understand: ‘… there is nothing further for this place.’”
