| "Those who are in devotional service of Kṛṣṇa, or the Supreme Lord, they are not interested in any planets of this material world. Why? Because they know. In any planet you can, you can raise yourself, you can elevate yourself, you can go there, but the four principles of material existence are there. What is that? Birth, death, disease and old age. Any planet you go. Your duration of life may be very, very longer than this earth, but death is there. Death is there."
