Vaishnava Samhita. Narayana Muni Charitam. Vol III Book VI Chp 21 Shloka 12

नापेक्षेते च संस्कारान् तथैव नियमान् बहून् |
केवलं प्रेमरूपा सा कृष्णसंयोगदायिनी ||

Such true bhakti is the very manifestation of true prem. Hence it automatically brings about union with Shri Krishna without any emphasis placed on rules and regulations, rites and rituals and austerities.
