Collected into this book are several confidential hints about devotional service. Bhaktivinoda Thakura was constantly reciting and relishing verses such as the ones in this book, and becoming overwhelmed with love of God. Devotees whose faith is on the neophyte platform, the system of arcana, diety worship, is provided. Arcana means to worship the deity with awe and reverence, with knowledge of the Lords opulence and by observing etiquette. It is also arcana to serve the Supreme Lord, with various paraphernalia according to rules and regulations and with the mundane conception of identifying oneself with the material body. Service rendered with intimacy and a sense of possessiveness, the hot rays are still apparent to a small degree, and no one can refuse the excellent sweetness of its cool, pleasant moonbeams.
