SB 11.3.20 — One cannot find permanent happiness even on the heavenly planets, which one can attain in the next life by ritualistic ceremonies and sacrifices. Even in material heaven the living entity is disturbed by rivalry with his equals and envy of those superior to him. And since one’s residence in heaven is finished with the exhaustion of pious fruitive activities, the denizens of heaven are afflicted by fear, anticipating the destruction of their heavenly life. Thus they resemble kings who, though enviously admired by ordinary citizens, are constantly harassed by enemy kings and who therefore never attain actual happiness.
