In plain words
Such a man can become not only a great soul but even Mahādeva.
The universe is the form of Viṣṇu
"Sahasraśīrṣāḥ puruṣaḥ sahasrākṣa sahasrapāt": all heads, all eyes, all feet are God's! The universe is the form of Viṣṇu. He lives keeping in view the truth: "The whole world is the very shape of God!" This the devotee holds as the non-duality of Prema; he contemplates the divine oneness of the jīva and Brahman with the feeling "So'ham". Such a devotee gives up even Mokṣa, and longs always for the Prema of God alone; this has been called "ananya Bhakti". Bhakti shows that along with the aims of life man pursues, Dharma, Artha, Kāma and Mokṣa, there is the duty of attaining a fifth aim as well. That is supreme Bhakti. Śaṅkara taught this too as "the mark of Jñāna". One need not grieve, "I have no acquaintance with the śāstras of karma yoga and the rest." In supreme Bhakti all the good qualities are contained.
The state of immortality is gained only through the principle of divine Prema
The Purāṇas take Mokṣa to mean merging in the divine. But the mark of Bhakti is the faith that in such oneness no Ānanda at all is found, and that Mokṣa is to spend one's time in living humanness, ever thinking of God and in communion with God. Vedānta has shown that the principle of Prema for God is itself Mokṣa. The heart of God is a principle sweeter than the sweetest. Sooner or later, at some time, every man must enter that mansion of Prema. Such a supreme devotee gives up Mokṣa. The supreme Bhakti of a man who has so given it up brings him into the lap of God.
