Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 5

Sanskrit:

तं त्वाखिलात्मदयितेश्वरमाश्रितानांसर्वार्थदं स्वकृतविद् विसृजेत को नु ।को वा भजेत् किमपि विस्मृतयेऽनु भूत्यैकिं वा भवेन्न तव पादरजोजुषां न: ॥ ५ ॥

ITRANS:

taṁ tvākhilātma-dayiteśvaram āśritānāṁsarvārtha-daṁ sva-kṛta-vid visṛjeta ko nuko vā bhajet kim api vismṛtaye ’nu bhūtyaikiṁ vā bhaven na tava pāda-rajo-juṣāṁ naḥ

Translation:

Who, then, could dare reject You, the very Soul, the most dear object of worship, and the Supreme Lord of all — You who give all possible perfections to the devotees who take shelter of You? Who could be so ungrateful, knowing the benefits You bestow? Who would reject You and accept something for the sake of material enjoyment, which simply leads to forgetfulness of You? And what lack is there for us who are engaged in the service of the dust of Your lotus feet?

Purport:

As stated in the Nārāyaṇīya of the Mokṣa-dharma, in Śrī Mahābhārata: “Whatever among the four goals of human life can be achieved by various spiritual practices is automatically achieved without such endeavors by the person who has taken shelter of Lord Nārāyaṇa, the refuge of all persons.” Thus a Kṛṣṇa conscious person knows that he will obtain all perfection of life simply by surrendering to the devotional service of Lord Kṛṣṇa. This is the highest stage of yoga, as confirmed in Bhagavad-gītā.
