The song "That Which I Have Lost" by George Harrison explores themes of seeking enlightenment, liberation from limitations, and the need for guidance in a spiritual journey. The protagonist of the song is depicted as an individual who is fighting against the forces of darkness, falsehood, and mortality. They feel bewildered and lost, unaware of the path they should take in order to regain their connection with the higher world. They long for someone to show them the way, to illuminate their consciousness and remove the darkness within them. Amidst this struggle, a transformative moment occurs when a light from Heaven breaks through, providing inward illumination. This experience enriches the protagonist's life, renewing their spirit and allowing them to see clearly again. The barriers that confined them start to crumble as they embrace this newfound clarity. In contrast, the people around the protagonist are preoccupied with fighting revolutions and remain stuck in the lower world. The protagonist perceives that they don't have the time or inclination to listen to their experiences or search for greater understanding. The mirrors of their understanding are clouded with desire and need cleansing before reflecting pure light. The song emphasizes the universal need for guidance and spiritual awakening. It suggests that everyone requires someone to show them the way, illuminate their consciousness, and help them overcome the darkness within. Harrison's lyrics convey the idea that true liberation comes from finding a mentor or guide who can help regain what has been lost spiritually.
