We have practical experience of this with our students in the International Society for Krishna Consciousness. Before becoming students, they were dirty looking, although they had naturally beautiful personal features; but due to having no information of Krṣṇa consciousness they appeared very dirty and wretched. Since they have taken to Krṣṇa consciousness, their health has improved, and by following the rules and regulations, their bodily luster has increased. When they are dressed with saffron colored cloth, with  tilaka  on their foreheads and beads in their hands and on their necks, they look exactly as if they come directly from Vaikuṇṭha.
The residents of the water are the fish, frogs, and so on, and the residents of the land are the cows, deer, and so on. By constantly drinking and taking bath in the fresh rain water of the rainy season, the tired and parched animals are re-freshed and their complexion becomes brilliant as their health is invigorated by the arrival of new rain water. The lakes, ponds and rivers are cleansed and invigorated by the down-pour of new rain water and thus become most beautiful. Similarly, a devotee of the Supreme Lord who takes advantage of the beautiful and invigorating downpour of the transcendental descriptions of God found in Vedic literature finds his spiritual consciousness invigorated and refreshed. In this way his spiritualized body becomes very beautiful.■
