(we reply:) “no”, because in the middle, the topic is the Supreme
Soul.
Vedānta-kaustubha
If it be objected: The individual soul is “not atomic”. Why?
“Because of the scriptural mention of what is not that,”—“that”
means atomicity, “what is not that” means non-atomicity, on account
of the scriptural mention of that,¹—i.e. because in connection with the
discourse on the individual soul, viz. ‘He who is made of knowledge
among the vital-breaths, who is the light within the soul’ (Bṛh. 4.3.7),
there is the mention of greatness in the scriptural text: ‘He, verily, is
the great, unborn soul’ (Bṛh. 4.4 25),—
(We reply:) “No”. Why? “On account of the topic being
something else,” i.e. because the topic is here something other than
the individual soul referred to in the beginning, i e the Supreme Soul,
who is the topic to be established in the middle of the section, in the
text: ‘By whom the soul has been found and realized’ (Bṛh. 4 4.13)
SŪTRA 22
“AND ON ACCOUNT OF THE WORD ITSELF AND OF MEASURE.”
Vedānta-pārijāta-saurabha
“On account of the word itself (viz. ‘atomic’) and of measure,”
mentioned (respectively) in the texts: ‘This atomic soul’ (Muṇḍ.
3 1.9²), ‘An individual soul is a part of the hundredth part of the
tip of a hair, divided a hundredfold’ (Śvet. 5.9³), the individual soul
is atomic.
Vedānta-kaustubha
The phrase: “the word itself” means the word which is denotative
of its own atomicity. The word “measure” means the measure which
is separated from⁴ all gross measures, i.e. an intensely minute measure.
On account of these two, the individual soul is atomic. The word
itself is mentioned in the text: ‘This atomic soul in which the five-fold
vital-breath has entered is to be known by means of thought’ (Muṇḍ.
