SŪTRA 19
"(THE INDIVIDUAL SOUL IS ATOMIC ON ACCOUNT OF THE SCRIPTURAL
MENTION) OF DEPARTURE, GOING AND RETURNING."
Vedānta-pārijāta-saurabha
The individual soul is atomic, because in the texts: 'By that
light this soul departs through the eye, or through the head, or through
other parts of the body' (Bṛh. 4.4 2¹), 'Whoever, verily, depart
from this world, all go to the moon alone' (Kauṣ. 1.2²), 'Having
come back from that world to this world for action' (Bṛh. 4 4 6³)
and so on, there is the mention "of departure, going and returning".
Vedānta-kaustubha
Thus, it has been proved that the individual soul is eternal and a
knower. Now its size is being determined.
On the doubt, viz. whether this soul is of a middle size,⁴ or of an
all-pervading size, or of an atomic size,—if it be suggested: It must
be of a middle size, since pleasure and the rest are experienced all
over the body. Or, it must be of an all-pervading size,—
We reply: The individual soul is capable "of departing, going
and returning". These three are not possible if it be all-pervading.
Moreover, if it be all-pervading, then experiences of pleasure and the
like will result everywhere. If, on the other hand, it be of a middle
size, then it must be non-eternal. Hence, the atomicity of the soul
is the only remaining alternative. In the passage: 'When he departs
from this body, he departs together with all these' (Kauṣ. 3.3⁵), its
departure is mentioned. In the passage: 'Whoever, verily, depart
from this world, all go to the moon alone' (Kauṣ. 1.2), its going
is mentioned. And, in the passage: 'Having come back from that
world to this world for action' (Bṛh. 4.4.6), its returning is mentioned.
