इत्यच्युताङ्घ्रि भजतोऽनुवृत्त्या
भक्तिर्विरक्तिर्भगवत्प्रबोध: ।
भवन्ति वै भागवतस्य राजं-
स्तत: परां शान्तिमुपैति साक्षात् ॥ ४३ ॥
ity acyutāṅghriṁ bhajato ’nuvṛttyā
bhaktir viraktir bhagavat-prabodhaḥ
bhavanti vai bhāgavatasya rājaṁs
tataḥ parāṁ śāntim upaiti sākṣāt
My dear King, the devotee who worships the lotus feet of the infallible Personality of Godhead with constant endeavor thus achieves unflinching devotion, detachment and experienced knowledge of the Personality of Godhead. In this way the successful devotee of the Lord achieves supreme spiritual peace.
