"Lord Caitanya likens transcendental devotional service to the sowing of a seed in the heart of the living entity. There are innumerable living entities traveling throughout the different planets of the universe, and out of them there are a few who are fortunate enough to meet a pure devotee and get the chance to understand devotional service. This 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 and chanting, Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare, that seed fructifies, just as the seed of a tree fructifies with regular watering. The spiritual plant of devotional service gradually grows and grows until it penetrates the covering of the material universe and enters into the brahmajyoti effulgence in the spiritual sky. In the spiritual sky also that plant grows more and more until it reaches the highest planet, which is called Goloka Vrndavana, the supreme planet of Krsna. Ultimately, the plant takes shelter under the lotus feet of Krsna and rests there."
