The Upanishads - Mandhata Global

Adi of that Saman.
5
What he is just at midday, that is the Udgitha. The devas
(gods) are dependent upon it. Therefore they are the best
of the offspring of Prajapati, for they partake of the
Udgitha of that Sa man.
6
What he is after midday and before afternoon, that is
the Pratihara. The foetuses depend upon it. Therefore
they are held in the womb after being conceived and do
not fall, for they partake of the Pratihara of the Saman.
What he is after the afternoon and before sunset, that is
the Upadrava. The animals of the forest depend upon it.
Therefore they run (upadravanti) to the forest and their
caves when they see a man, for partake of the Upadrava
of that Saman.
8
What he is just after the sunset, that is the Nidhana. The
Manes depend upon it. Therefore they put them (i.e. the
Manes) down (nidadhati), for they partake of the
Nidhana of that Saman. Thus a man meditates on the
sevenfold Saman as the sun.
