तस्मादन्यद्भगवद्भजनमपि नापेक्षते ।
tasmād anyad bhagavad-bhajanam api nāpekṣate |
(Bhakti Sandarbha: 237)
“Therefore [i.e., because Hari can become pleased to reveal himself simply in response to guru-bhakti], even other service to Bhagavān is not required [for a sādhaka fully engaged in personal service to his guru].”
