Who is speaking and story frame
पुरैव पुंसावधृतो धराज्वरोभवद्भिरंशैर्यदुषूपजन्यताम् । स यावदुर्व्या भरमीश्वरेश्वर:स्वकालशक्त्या क्षपयंश्चरेद् भुवि ॥ २२ ॥
puraiva puṁsāvadhṛto dharā-jvaro
bhavadbhir aṁśair yaduṣūpajanyatām
sa yāvad urvyā bharam īśvareśvaraḥ
sva-kāla-śaktyā kṣapayaṁś cared bhuvi
Lord Brahmā informed the demigods: Before we submitted our petition to the Lord, He was already aware of the distress on earth. Consequently, for as long as the Lord moves on earth to diminish its burden by His own potency in the form of time, all of you demigods should appear through plenary portions as sons and grandsons in the family of the Yadus.
