Who is speaking and story frame
इति मां य: स्वधर्मेण भजेन् नित्यमनन्यभाक् ।
सर्वभूतेषु मद्भावो मद्भक्तिं विन्दते दृढाम् ॥ ४४ ॥
iti māṁ yaḥ sva-dharmeṇa
bhajen nityam ananya-bhāk
sarva-bhūteṣu mad-bhāvo
mad-bhaktiṁ vindate dṛḍhām
One who worships Me by his prescribed duty, having no other object of worship, and who remains conscious of Me as present in all living entities, achieves unflinching devotional service unto Me.
