Adhikaraṇa 7
"Vaiśvānara" is the Supreme Personality of Godhead
Introduction by Śrīla Baladeva Vidyābhūṣaṇa
Viṣaya: The Chāndogya Upaniṣad says (5.11.1): ko nu ātmā kiṁ brahmeti (Who is
the ātmā? Who is the Supreme Personality of Godhead?), and (5.11.6) ātmānaṁ
evaṁ vaiśvānaraṁ sampraty adhyeṣi tam eva no brūhi (You know about Vaiśvānara.
Please describe Him.) and (5.18.1) yas tv enam evaṁ prādeśa-mātram abhivimānam
ātmānaṁ vaiśvānaraṁ upāste sa sarveṣu lokeṣu sarveṣu bhūteṣu sarveṣu ātmasu
annam atti (One who meditates on Vaiśvānara, who is the size of the distance
between the thumb and forefinger, and who is present in all worlds, in all
elements, and in all hearts, eats food and is nourished.) and (5.18.2) etasya ha vā
etasyātmano vaiśvānarasya mūrdhaiva su-tejāś cakṣur viśvarūpaḥ prāṇaḥ pṛthag-
vartmā sandeho bahulo vastir eva vayiḥ pṛthivy eva pādāv ura eva vedir lomānir bahir
hṛdayaṁ gārhapatyo mano 'nvāhāryapacana āsyaṁ āhavanīyaḥ (Heaven is the head of
Vaiśvānara, the sun is His eye, the wind is His breath, the sky is His body, the
oceans are His bladder, the earth is His feet, the sacrificial arena is His chest, the
sacrificial grass is His head, the gārhapatya fire is His heart, the anvāhāryapacana
fire is His mind, and the āhavanīya fire is His mouth).
Saṁśaya: Is the Vaiśvānara the fire of digestion, the demigod Agni, the fire
element, or Lord Viṣṇu? Pūrvapakṣa: The word vaiśvānara is commonly used in
all these four meanings, so its meaning in this passage is unclear.
Siddhānta: The conclusion follows.
Sūtra 25
vaiśvānaraḥ sādharaṇa-śabda-viśeṣāt
vaiśvānaraḥ—Vaiśvānara; sādharaṇa—common; śabda—word; viśeṣāt—because of
the distinction.
