Acharya Prashant provides a profound interpretation of Kabir Saheb's words, explaining that 'light' in spirituality signifies knowledge that dispels the darkness of the mind, rather than physical illumination. He identifies the 'ego-tendency' as the primary darkness, which resides within the body and its cells. True self-knowledge involves recognizing that all experiences, emotions, and perceptions of the external world are rooted in the body. He argues that the entire universe is dependent on the observer's senses; if the senses do not validate an object, it effectively does not exist for the individual. Therefore, understanding the body and the ego-tendency is the key to understanding the entire cosmos.
