One way for attaining Bhakti is by repeating the name of God a number of times. Mantras have effect: the mere repetition of words.... To obtain Bhakti, seek the company of holy men who have Bhakti, and read books like the Gita and the Imitation of Christ; always think of the attributes of God.
Swami VivekanandaThose who work at a thing heart and soul not only achieve success in it but through their absorption in that they also realize the supreme truth-Brahman. Those who work at a thing with their whole heart receive help from God.
Swami VivekanandaThe first angle is, love questions not. It is not a beggar. ... When love asks nothing, [when it] gives everything. This is the real spiritual worship, the worship through love. Whether God is merciful is no longer questioned. He is God; He is my love. Whether God is omnipotent and almighty, limited or unlimited , is no longer questioned.
