The devotional service is just like a seed, and if it is sown in the heart of a living entity, and if he goes on hearing "Hare Krsna Hare Krsna Krsna Krsna Hare Hare / Hare Rama Hare Rama Rama Rama Hare Hare" mantra, that seed fructifies, just as a seed of a tree fructifies with regular watering. The spiritual plant of devotional service gradually grows by chanting and hearing of His holy names and helps one to achieve the goal of human life - love of Godhead.
