The most dangerous of the dirty things within our hearts
The most dangerous of the dirty things within our hearts is this misidentification of the body as the self. Under the influence of this misunderstanding, one thinks, “I am this body. I am an Englishman. I am an Indian. I am an American. I am Hindu. I am Muslim.” This misconception is the strongest impediment, and it must be removed. That is the instruction of Bhagavad-gita and of Sri Caitanya Mahaprabhu.
