首楞嚴義疏注經 2.46

2.46

佛言：「大王！如汝所說，二十之時衰於十歲，乃至六十，日月歲時念念遷變，則汝三歲見此河時，至年十三其水云何？」王言：「如三歲時宛然無異，乃至于今年六十二亦無有異。」

The Buddha said, 'Great King! As you have said, at twenty you declined compared to ten, and so on up to sixty, with months, days, years, and seasons shifting and changing from moment to moment; then when you were three years old and saw this river, compared to when you were thirteen, how was its water?' The king said, 'It was just as when I was three years old, with no difference at all, and even up to now at sixty-two years of age, there is no difference.'
