Book excerpt: The word Brahm means the Absolute or Ultimate Reality that is the primal cause of the existence of the universe and all beings. Nirupan means the form or nature of that Reality. For simplicity, we can say God. Yet we know that God is beyond forms and attributes that we can ascribe to Him. But we need to use words to communicate, so Kabir explains to his disciple that the Ultimate cannot be described in words, but must be experienced inwardly. He then describes various methods of approaching God, the negative actions to avoid, and the virtuous ones to be cultivated, as one progresses on the spiritual path to enlightenment. Kabir uses several Indian analogies and metaphors to explain the teachings to his earnest disciple.
