कृष्णभक्त्यैव साधुत्वं साधनं परमं हि सा ।
तया साध्यं तदङ्घ्र्यब्जयुगलं परमं फलम् ॥
kṛṣṇa-bhaktyaiva sādhutvaṁ sādhanaṁ paramaṁ hi sā |
tayā sādhyaṁ tad-aṅghry-abja-yugalaṁ paramaṁ phalam ||
(Bṛhad Bhāgavatāmṛta: 2.2.202)
“Sādhutva [i.e., the state of being sādhu] comes about only by Kṛṣṇa-bhakti, since that [i.e., Kṛṣṇa-bhakti] is the supreme sādhana, and by that the supreme goal, his two lotus feet, is attainable.”
