In plain words
Bhakti alone bestows the highest goal; Bhakti alone destroys the delusion of worldly life; Bhakti alone grants the knowledge of the Supreme; Bhakti alone brings the supreme Mokṣa.
Embodiments of Prema!
It is through Bhakti that man is able to attain the supreme principle. It is through Bhakti that he is able to put an end to birth and death, the disease of worldly existence. It is through Bhakti that he strives to recognise the principle of the Paramātma. It is through Bhakti that he attains the supreme state. Regarding Bhakti as the highest sādhana, trusting it as the highest destination, holding it as the highest aim, the people of Bhārata have followed this path from time without beginning. ‘Bhakti’ has been understood in many senses. The word Bhakti arises from the root ‘bhaj’. ‘Bhaj sevāyām’, said Śaṅkara. Service is what is called ‘Bhakti’. Whose service, what kind of service (what does bhaj sevāyām mean)? The principle of God has many definitions. ‘Service of God is true Bhakti’: so the spiritual wisdom of Bhārata has shown. The Vivekacūḍāmaṇi has taught it another way. ‘The vision of one's own svarūpa is Bhakti’, it said. Then Nārada, teaching the glory of this Bhakti in boundless measure, defined it: ‘Supreme Prema is Bhakti.’ To steep the Name of God in Prema, in an unbroken stream, and turn that flow of Prema towards God: that is Bhakti, they said.
Feelings may change; the heart does not change
This principle of Prema makes one forget the body, delights one, dissolves one into the mind and fills one with absorption.
