"On one occasion the sage was going forth from their cottage in a great hurry. The nymph asked him where he was going. 'The day,' he replied, 'is drawing fast to a close: I must perform the Sandhya worship, or a duty will be neglected.' The nymph smiled mirthfully as she rejoined, 'Why do you talk, grave sir, of this day drawing to a close: your day is a day of many years, a day that must be a marvel to all: explain what this means.' The Muni said, 'Fair damsel, you came to the river-side at dawn; I beheld you then, and you then entered my hermitage. It is now the revolution of evening, and the day is gone. What is the meaning of this laughter? Tell me the truth.' Pramlochá. answered, 'You say rightly,' venerable Brahman, 'that I came hither at morning dawn, but several hundred years have passed since the time of my arrival. This is the truth.' The Muni, on hearing this, was seized with astonishment, and asked her how long he had enjoyed her society: to which the nymph replied, that they had lived together nine hundred and seven years, six months, and three days. The Muni asked her if she spoke the truth, or if she was in jest; for it appeared to him that they had spent but one day together: to which Pramlochá replied, that she should not dare at any time to tell him who lived in the path of piety an untruth, but particularly when she had been enjoined by him to inform him what had passed.
