tasmād vairānubandhena nirvaireṇa bhayena vā
tasmād vairānubandhena nirvaireṇa bhayena vā |
snehāt kāmena vā yuñjyāt kathañcin nekṣate pṛthak ||
(Śrīmad Bhaṅavatam: 7.1.25)
“[Nārada Ṛṣi to Yudhiṣṭhira Mahārāja:] Therefore, by constant enmity, by non-enmity, by fear, by affection, or by amorous desire, one can connect [the mind to Bhagavān] such that one does not see [anything] apart [from Bhagavān] by any means.”
