"Supplication, worship, prayer are no superstition; they are acts more real than the acts of eating, drinking, sitting or walking. It is no exaggeration to say that they alone are real, all else is unreal.
Such worship or prayer is no flight of eloquence; it is no lip-homage. It springs from the heart. If, therefore, we achieve that purity of the heart when it is "emptied of all but love", if we keep all the chords in proper tune, they "trembling pass in music out of sight". Prayer needs no speech. It is in itself independent of any sensuous effort.
I have not the slightest doubt that prayer is an unfailing means of cleansing the heart of passions. But it must be combined with the utmost humility."
Mohandas Karamchand Gandhi
