स्वर्गिणोऽप्येतमिच्छन्ति लोकं निरयिणस्तथा । साधकं ज्ञानभक्तिभ्यामुभयं तदसाधकम् ॥ १२ ॥

svargiṇo ’py etam icchanti lokaṁ nirayiṇas tathā sādhakaṁ jñāna-bhaktibhyām ubhayaṁ tad-asādhakam

icchanti
desire
lokam

nirayiṇaḥ
the residents of hell
tathā
in the same way

The residents of both heaven and hell desire human birth on the earth planet because human life facilitates the achievement of transcendental knowledge and love of Godhead, whereas neither heavenly nor hellish bodies efficiently provide such opportunities.
