yatra eṣām mokṣecchā kadāpi na asti — since in these there is never any wish for liberation; ata eva — therefore; ete pañcavidha-mukteṣu sudurlabhāḥ — they are very rare even among holders of the five liberations; iti āha — this he says; ata eva śrī-bhāgavate ṣaṣṭhe iti ādi śloka-trayyā — by the three verses beginning "therefore, in the Sixth Book…"; muktānām — "of the liberated" = ; dehasthatva eva prāpta-brahma-bhāvānām — of those who reached Brahman while still in the body; prāpta-sālokyādi-caturdhā-muktīnām api — and even of those with the fourfold sālokya-etc. liberation; koṭiṣu madhye — among ten million
Mukunda first tells us why Rūpa brings in this quotation. In these pure devotees there is never, at any moment, even a wish for liberation. That is exactly why they are rarer than the people who hold the five kinds of liberation. To say this, Rūpa cites the passage beginning "therefore, in the Sixth Book of the Bhāgavata…" — and it is a set of three verses, not one. Then Mukunda explains the verse's words. "The liberated" means those who, even while still in the body, have already reached the state of Brahman. And it includes even those who have won the fourfold liberation that begins with sālokya. The rarity is counted among ten million of these.
Why cited: Names the purpose of Rūpa's quotation — to show the desireless devotee is rarer than any holder of the five liberations — and flags that it is a set of three verses.
pañcavidha-mukti / caturdhā-mukti: the five liberations are sālokya, sāmīpya, sārūpya, sārṣṭi, sāyujya; "fourfold" counts the first four (the personal ones), often set apart from sāyujya (merging). Mukunda uses both counts here without contradiction — five when including sāyujya, four for the sālokya-group.
