Devotional service rendered to the devotee bestows the highest fruit –

“O Supreme Lord of all beings, O slayer of the demons Madhu and Kaitabha, this is the purpose of my life, this is my prayer, and this is Your grace – that You will remember me as Your servant, a servant of a servant of a Vaisnava, a servant of a servant of such a servant of a servant of a Vaisnava, and a servant of a servant of the servant of a servant of a Vaisnava’s servant’s servant.” – Sri Kulasekhara

[from Srila Bhakti Rakshak Sridhar, Sri Prapanna Jivanamrtam 3.13]
