True prayer is mental utterance in secret.

Book excerpt: True prayer is unselfish love of humanity. It is an act of will and a command but, unless enacted, prayer is pathetic. Prayers should be for blessings on all that lives. We shall be able to pray to Him properly, only when we approach by ourselves alone to the Alone. Our prayers and supplications are vain, unless to potential words we add potent acts. And thus make the aura which surrounds each one of us so pure and divine that the God within us may act outwardly, or in other words, become as it were an extraneous potency. To produce beneficial effects, the prayer must be uttered by “one who knows how to make himself heard in silence,” when it is no longer a “prayer” but a command. A clear conscience and a firm desire of benefiting humanity afford the best protection from air elementals, which throng public places. Loud prayers are disastrous. Woe to the unholy man who invokes the Sacred Trinity for personal advancement or pronounces It after the commission of some far-reaching sin. The Devotional Prayers of Chaitanya Mahaprabhu and Alexander Pope.
