Srimad Bhagavatam 5.11.8br by HG Navina Nirada Dasa 182022br Everyone is suffering in this material world because of the mind. When the flame in a lamp burns the wick improperly, the lamp is blackened, but when the lamp is filled with ghee and is burning properly, there is bright illumination. Similarly, when the mind is absorbed in material sense gratification, it causes suffering, and when detached from material sense gratification it brings about the original brightness of Krsna consciousness.
