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

which consists of bliss) has no other (inner) soul.¹ The expression
'Let them be purified' (in the above Mahānārāyaṇa passage) means
'Let them be embellished'

If it be objected: That which consists of bliss cannot be the
Highest Self. Why ? "On account of the word denoting modifica-

the sense of 'modification',—beginning: 'Mayaṭ is used optionally
in the classical language after any base (to indicate "product" and

breath as its inner soul; this latter again has the soul consisting of mind as its
inner soul; this latter again has the soul consisting of understanding as its inner
soul, and this latter again has the soul consisting of bliss as its inner soul But
the last one, viz. the soul consisting of bliss, has nothing else as its soul, but is
the inmost soul of all,
