The next forty-four years are the midday-libation. The Trishtubh has forty-four syllables, the midday-libation is offered with Trishtubh hymns. The Rudras are connected with that part of it. The Prânas are the Rudras, for they make all this to cry (rodayanti).

In plain words: The next 44 years of life are compared to the midday offering of a great ritual. The life-breaths in this stage are linked to the Rudras, storm gods, because they make people cry.
