Srimad-Bhagavatam: Canto 7 - Chapter 1 - Verse 10
ॐ नमो भगवते तुभ्यं पुरुषाय महात्मने ।हरयेऽद्भुतसिंहाय ब्रह्मणे परमात्मने ॥ १० ॥
oṁ namo bhagavate tubhyaṁpuruṣāya mahātmaneharaye ’dbhuta-siṁhāyabrahmaṇe paramātmane
O my Lord, full of six opulences, O Supreme Person! O Supreme Soul, killer of all miseries! O Supreme Person in the form of a wonderful lion and man, let me offer my respectful obeisances unto You.
In the previous verse Prahlāda Mahārāja has explained that a devotee can achieve the platform of bhagavattva, being as good as the Supreme Person, but this does not mean that the devotee loses his position as a servant. A pure servant of the Lord, although as opulent as the Lord, is still meant to offer respectful obeisances to the Lord in service. Prahlāda Mahārāja was engaged in pacifying the Lord, and therefore he did not consider himself equal to the Lord. He defined his position as a servant and offered respectful obeisances unto the Lord.
