[127] "Rāhula, suppose there were a king's bull elephant (nāga), with tusks like chariot-poles (īsādanta), grown to mighty stature and of noble breed, accustomed to battle. Gone into battle, it performs its work with its fore-feet, performs its work with its hind-feet, performs its work with its fore-quarters, performs its work with its hind-quarters, performs its work with its head, performs its work with its ears, performs its work with its tusks, performs its work with its tail — yet it still protects its trunk. Thereupon the elephant-rider thinks thus: 'This king's bull elephant, with tusks like chariot-poles, grown to mighty stature and of noble breed, accustomed to battle, gone into battle, performs its work with its fore-feet, performs its work with its hind-feet, performs its work with its fore-quarters, performs its work with its hind-quarters, performs its work with its head, performs its work with its ears, performs its work with its tusks, performs its work with its tail — yet it still protects its trunk. The king's bull elephant has not yet given up its life.' But, Rāhula, when the king's bull elephant, with tusks like chariot-poles, grown to mighty stature and of noble breed, accustomed to battle, gone into battle, performs its work with its fore-feet, performs its work with its hind-feet … performs its work with its tail, and performs its work with its trunk as well, thereupon the elephant-rider thinks thus: 'This king's bull elephant, with tusks like chariot-poles, grown to mighty stature and of noble breed, accustomed to battle, gone into battle, performs its work with its fore-feet, performs its work with its hind-feet, performs its work with its fore-quarters, performs its work with its hind-quarters, performs its work with its head, performs its work with its ears, performs its work with its tusks, performs its work with its tail, and performs its work with its trunk as well. The king's bull elephant has given up its life; there is now nothing that the king's bull elephant would not do.' Even so, Rāhula, for anyone who feels no shame in deliberate false speech (sampajānamusāvāda), there is no evil deed whatsoever, I say, that he would not do. Therefore, Rāhula, you should train yourself thus: 'I will not speak falsehood even in jest.' Thus indeed, Rāhula, should you train yourself."
