How is bhakti is known as subha-da, the bestower of good fortune?
The word subha, good fortune and auspiciousness, means to ascend to a position of attracting the love and respect of everyone, to have available all varieties of pleasures and comforts that bring joy, and to be adorned with all good qualities. When the heart is imbued with suddha-bhakti, the four qualities of humility, compassion, pridelessness, and magnanimous respect decorate the character of the jiva. As a result, the jiva is loved and respected by everyone in the world. All the sad-gunas, good qualities, automatically manifest in the personality of a devotee. Bhakti is competent to bestow upon the devotee all pleasures and comforts, even material ones, plus the pleasure of impersonal Brahman realization, plus all the yoga-siddhis, mystic perfections. The devotees, however, are not attracted to any of these, and so suddha-bhakti rewards the pure devotee with the rarest and paramount bliss- eternal, unlimited ecstasy in the service of Bhagavan
