Scripture directly applies the word 'anu' to the individual Self, 'By
thought is to be known that atomic Self into which Breath has entered
fivefold' (Mu. Up. III, 1, 9).--By the term 'unmâna' in the Sûtra we
have to understand measurement by selection of comparative instances.
Scripture declares the minuteness of the individual Self by reference to
things which are like atoms in size, 'The individual soul is to be known
as part of the hundredth part of the point of a hair divided a hundred
times, and yet it is to be infinite' (Svet. Up. V, 9); 'that lower one
is seen of the measure of the point of a goad' (V, 8). For these reasons
also the individual Self must be viewed as atomic.--But this conflicts
with the fact that sensation extends over the whole body!--This
objection the next Sûtra refutes by means of an analogous instance.
