यत्र रागानवाप्तत्वात्प्रवृत्तिरुपजायते ।
शासनेनैव शास्त्रस्य सा वैधी भक्तिरुच्यते ॥
yatra rāgānavāptatvāt pravṛttir upajāyate |
śāsanenaiva śāstrasya sā vaidhī bhaktir ucyate ||
(Bhakti-rasāmṛta-sindhu: 1.2.6)
“That [type of sādhana-bhakti] in which the motivation [for engaging in bhakti] is produced not because of the attainment liking (rāga) [for bhakti] but only by the ruling of śāstra is called vaidhī-sādhana-bhakti.”
