he who is the chief vital-breath,—him they worshipped as the udgītha"
(Chānd. 1.2.7). They, further, state the fruit of the knowledge thus:
"So exactly he falls to pieces who wishes evil to one who knows thus"
(Chānd 1.2.8 ¹)
On the doubt, viz whether here the vidyās are identical or
different,—we (i.e. prima facie objectors) say: The vidyās are the
same. Why? "On account of the non-difference" of injunctions
and the rest. Thus, the injunction, expressed by the root 'to know',
is the same, the fruit too, viz the overcoming of the demons, is
the same; the form, as well, is the same as the object to be meditated
on, viz the udgītha viewed as the vital-breath, is so; and the name,
too, viz. 'udgītha-meditation' is the same.
If it be objected: There is "difference", i.e. there is difference
from the admitted sameness of the vidyās, i.e. the vidyās are not
identical. Why? In the text: " 'Sing the udgītha for us.' That
breath sang the udgītha" (Bṛh. 1.3.7), the vital-breath is indicated
as a subject by the Vājins by a word in the nominative case. But in
the text: "Him, the udgītha" (Chānd. 1.2.7), it is described as an
object, having the form of the udgītha, by the Chāndogas by a word
in the accusative case,—on account of such scriptural texts,—

and Chāndogya.—
(a) Bṛh. 1.3.—The story begins: The gods and the demons, the offspring
of Prajāpati fought with one another for the worlds. The gods, then resolved
to overcome the demons at the sacrifice by the udgītha. So they asked speech
to sing the udgītha for them. But the demons, coming to know of this, rushed
upon it and pierced it with evil. Thereupon the gods successively approached
the in-breath, the eye, the ear and the mind, each of which was however corrupted
by the demons. Finally, they approached the chief vital-breath which sang
the udgītha for them, and when the demons rushed upon it, trying to pierce
it with evil, they themselves were scattered and perished (Bṛh. 1.3.1–1.3.7).
(b) Chānd. 1.2.—A very similar account given. The story begins: The
gods and the demons, the offspring of Prajāpati fought with one another, and the
gods took the udgītha, thinking that they would overcome the demons with it.
Then they worshipped the breath in the nose as the udgītha, but the demons
pierced it with evil. Thereupon, they successively worshipped as the udgītha
speech, the eye, the ear and the mind, each of which were, however, corrupted
by the demons. Finally, they worshipped the chief vital-breath as the udgītha,
and when the demons tried to corrupt it, they themselves fell to pieces (Chānd
1.2.1–1.2.7).
