तदेकस्पृहत्वमेव रतेर्लक्षणं मुख्यमिइत्युक्तम् |
tad-eka-spṛhatvam eva rater lakṣaṇaṁ mukhyam ity uktam |
(Durgama-saṅgamī-ṭīkā to Bhakti-rasāmṛta-sindhi: 1.3.41)
“It is stated that desirousness only of him [i.e., Bhagavān] is truly the primary characteristic of rati [i.e., merely inner softness that manifests sāttvika-bhāvas, such as crying and trembling, is not the primary characteristic, since this can also be observed in persons engaged in impure forms of bhakti].”
