The next forty-eight years are the third libation. The Gagatî has forty-eight syllables, the third libation is offered with Gagatî hymns. The Âdityas are connected with that part of it. The Prânas are the Âdityas, for they take up all this (âdadate).

In plain words: The last 48 years of life are compared to the evening offering of the ritual. The life-breaths in this stage are linked to the Âdityas, sun gods, because they gather everything up.
