In plain words
In the ceaseless singing of Hari's Name, he let his heart be stolen away. In hardships, in sorrows, in torments too, this Prahlāda went on thinking ceaselessly of the Name of Hari alone: Namo Nārāyaṇā. However many ways the demons tormented him, he gave no room in his heart to sorrow or to grief, and kept his heart filled ceaselessly with Ānanda alone.
As the night-prowlers stab him, the Daitya's son, again and again, ‘O You who recline on the Serpent! O Destroyer of demons! O Lord of the world! O Refuge of those in great distress! O Purifier of all!’ So he praises; but he sheds no tears from his eyes, nor trembles with fear, O king!
The body is made of the five elements; the body must surely fall; the dweller in the body is free of ill; reckon it, and for the dweller in the body death and birth and the stamps of the bonds that delusion binds are not; seen in truth, that dweller in the body is the God of gods, of the very form of the Ātma, if you reflect in your mind.
To Prahlāda, who had turned his gaze to the principle of God, how would the thought of the body appear? The body is not his own. It is only like a bubble of water. It came into being so that through the body one may reach the One who dwells in it. So the one who, with no awareness of this body at all, ceaselessly thought of Hari alone and made his life worthwhile was this emperor Prahlāda.
Serving the feet. This is not something within everyone's reach. Even when it is within reach, one may go on serving the feet with some worldly outlook or other. But the one who dedicated her mind to this service, who regarded these feet as the measure and the mainstay of all creation, who saw them as the very feet that Brahmā washed, who believed them to be the feet that took in the whole world, who believed these feet to be the divine feet pervading everywhere, and who thought, ‘Such service alone is my sādhana’: that was Lakṣmī. So, in serving the feet, Lakṣmī made her life worthwhile.
Worship. For this worship, Emperor Pṛthu. At all times and in every state, he knew no worship whatever other than the worship of Hari. Viśvaṃ viṣṇusvarūpaṃ. Sahasraśīrṣā puruṣaḥ sahasrākṣa sahasrapāt. He alone is the one with many heads, many eyes and many feet. All the beings in the world are parts of the Paramātma.
