The Process of Devotional Service
१३३
vidaḥ —experts in reciting the Vedic hymns;  su-maṅgalāḥ —very auspicious;  kṣemam —real, eternal auspiciousness;  na —never;  vindanti —obtain;  vinā —without;  yat-arpaṇam —dedicating unto whom (the Supreme Personality of Godhead);  tasmai —unto that Supreme Personality of Godhead;  su-bhadra śravase —whose glory is very auspicious;  namaḥ namaḥ —I offer my repeated respectful obeisances.
TRANSLATION
“Those who perform severe austerities and penances, those who give away all their possessions out of charity, those who are very famous for their auspicious activity, those who are engaged in meditation and mental speculation, and even those who are very expert in reciting the Vedic mantras, are not able to obtain any auspicious results, although they are engaged in auspicious activities, if they do not dedicate their activities to the service of the Supreme Personality of Godhead. I therefore repeatedly offer my respectful obeisances unto the Supreme Personality of Godhead, whose glories are always auspicious.”

TEXT 21
কেবল জ্ঞান ‘মুক্তি’ দিতে নারে ভক্তি বিনে । কৃষ্ণোদ্মুখে সেই মুক্তি হয় বিনা জ্ঞানে ॥ ২১ ॥
kevala jñāna ‘mukti’ dite nāre bhakti vine kṛṣṇonmukhe sei mukti haya vinā jñāne
SYNONYMS
kevala —only;  jñāna —speculative knowledge;  mukti —liberation;  dite —to deliver;  nāre —is not able;  bhakti vine —without devotional service;  kṛṣṇa-un-mukhe —if one is attached to the service of Lord Kṛṣṇa;  sei mukti —that liberation;  haya —appears;  vinā —without;  jñāne —knowledge.
TRANSLATION
“Speculative knowledge alone, without devotional service, is not able to give liberation. On the other hand, even without knowledge one can obtain liberation if one engages in the Lord’s devotional service.
