"Lord Krishna, in the Gita, also informs us that this material world is full of miseries in the shape of birth, old age, disease and death. Even in the topmost planet of the material universe, Brahmaloka, these miseries are present. Only in His own abode is there no need of light from sun, moon or fire. The planets are self-luminous. Life there is perpetual and full of knowledge and bliss. That is what is known as sanatana-dharma. It is therefore natural to conclude that the living entities must return home, back to Godhead, to enjoy life in the sanatana-dharma with the sanatana-purusa or the purusottama, Lord Sri Krishna. They must not remain to rot in this miserable land of material existence."
