[322] On one occasion the Blessed One was dwelling at Ajjheyya, on the bank of the river Gaṅgā. The Blessed One saw a great log being carried along by the current on the river Gaṅgā, and having seen it, he addressed the bhikkhus: "Bhikkhus, do you see that great log being carried along by the current of the river Gaṅgā?" "Yes, venerable sir."
"Bhikkhus, if that log does not veer towards the near shore, does not veer towards the far shore, does not sink in mid-stream, does not get cast up on high ground, is not seized by humans, is not seized by non-humans, is not seized by a whirlpool, and does not become rotten within — in such a way, bhikkhus, that log will slant towards the ocean, slope towards the ocean, incline towards the ocean. For what reason? Because, bhikkhus, the current of the river Gaṅgā slants towards the ocean, slopes towards the ocean, inclines towards the ocean. Even so, bhikkhus, if you too do not veer towards the near shore, do not veer towards the far shore, do not sink in mid-stream, do not get cast up on high ground, are not seized by humans, are not seized by non-humans, are not seized by a whirlpool, and do not become rotten within — in such a way, bhikkhus, you will slant towards Nibbāna, slope towards Nibbāna, incline towards Nibbāna. For what reason? Because, bhikkhus, right view (sammādiṭṭhi) slants towards Nibbāna, slopes towards Nibbāna, inclines towards Nibbāna."
