[59] Then, Vāseṭṭhas, when the bursting pods (padālatā) of those beings had vanished, rice ripening in untilled ground (akaṭṭhapāko sāli) appeared — without powder, without husk, pure, fragrant, with the grain ready as rice. Whatever they gathered in the evening for the evening meal, by morning it had ripened and grown back again; whatever they gathered in the morning for the morning meal, by evening it had ripened and grown back again; no trace of reaping was to be seen. Then, Vāseṭṭhas, those beings, eating the rice that ripened in untilled ground, feeding on it, having it as their nourishment, endured for a long, long stretch of time. And, Vāseṭṭhas, in whatever measure those beings, eating the rice that ripened in untilled ground, feeding on it, having it as their nourishment, endured for a long, long stretch of time, in that measure coarseness descended still further into their bodies, and divergence of appearance became discernible. For the woman, female characteristics appeared, and for the man, male characteristics. And the woman gazed overlong at the man, and the man at the woman. As they gazed overlong at one another, lust arose, and a fever descended into their bodies. Because of that fever, they engaged in sexual intercourse (methuna dhamma).
Now, Vāseṭṭhas, those beings who at that time saw them engaging in sexual intercourse — some threw dust, some threw ashes, some threw cow-dung, saying: 'Perish, filthy one! Perish, filthy one! How indeed can one being do such a thing to another being?' And even today, in some countries, when a condemned woman is being carried off, people throw dust, some throw ashes, some throw cow-dung. They are merely recalling that same ancient, primordial expression, but they do not understand its meaning.
