Who is speaking and story frame
केचनैतज्ज्योतिरनीकं शिशुमारसंस्थानेन भगवतो वासुदेवस्य योगधारणायामनुवर्णयन्ति ॥ ४ ॥
kecanaitaj jyotir-anīkaṁ śiśumāra-saṁsthānena bhagavato vāsudevasya yoga-dhāraṇāyām anuvarṇayanti.
This great machine, consisting of the stars and planets, resembles the form of a śiśumāra [dolphin] in the water. It is sometimes considered an incarnation of Kṛṣṇa, Vāsudeva. Great yogīs meditate upon Vāsudeva in this form because it is actually visible.
