सूर्यकान्तेर्रवेर्योगाद्वह्निस्तत्र प्रजायते ।
एवं वै साधुसंयोगाद्धरौ भक्तिः प्रजायते ॥
sūryakānter raver yogād vahnis tatra prajāyate |
evaṁ vai sādhu-saṁyogād dharau bhaktiḥ prajāyate ||
(Padma Purāṇa: 6.132.13)
“Fire manifests there from the combination of a sun-crystal [lsy., a magnifying class] and the sun. Similarly, bhakti to Hari verily manifests from association with a sādhu.”
