वेदान्त पारिजात सौरभ (भगवद् निम्बार्काचार्य - द्वैताद्वैत वेदान्त ब्रह्मसूत्र भाष्य सटीक)

[SŪ. 1 3. 41]
ADH. 6 resumed.] VEDĀNTA-PĀRIJĀTA-SAURABHA 205
The words ‘what is measured’ are to be supplied. In the Kaṭha-
vallī, we find the following in the section of the Person, of the size of
merely a thumb ‘Whatever there is, the whole world, emanated
(from the vital-breath), trembles in the vital-breath alone, the great
fear, a thunderbolt about to be hurled. Those who know that become
immortal’ (Kaṭha 6. 2). Here, what is measured as of the size of a
thumb and is denoted by the term ‘vital-breath’ is none but the
Supreme Being. Why? For the following reasons: First, “on
account of the shaking”, i. e. the Lord alone is the cause of the shaking
of the entire universe, emanated from Himself. Secondly, the term
‘great’, which is a synonym for Brahman, has been used. Thirdly,
the term ‘fear’ proves that the vital-breath is Brahman, for He alone
is the cause of the fear of all, as declared by the text: ‘Through fear
of him the fire burns, through fear the sun shines, through fear Indra,
Wind and Death, the fifth, speed on’ (Kaṭha 6. 3), and finally, the
Lord alone is the cause of the immortality of one who possesses know-
ledge of Him.
COMPARISON
Śaṃkara, Bhāskara and Śrīkaṇṭha
Interpretation different, viz. they take this sūtra as forming a
new adhikaraṇa by itself, concerned with the question whether the
term ‘prāṇa’ in Kaṭha-upaniṣad (6.2) denotes Brahman or not. But
according to Nimbārka, this sūtra does not begin a new adhikaraṇa,
but only resumes adhikaraṇa 6.
Baladeva
Interpretation different, viz he also begins a new adhikaraṇa
here, concerned with the question whether the term ‘vajra’ in Kaṭha-
upaniṣad (6. 2) denotes Brahman or not.
SŪTRA 41
“BECAUSE OF PERCEIVING LIGHT.”
Vedānta-pārijāta-saurabha
Because in the text: ‘Through his light’ (Kaṭha 5.15¹), ‘light’
is mentioned, the measured Person is the Supreme Being.
