Acharya Prashant explains that light, representing knowledge and realization, is often misunderstood in human life. People generally seek light not for its own sake, but to better serve and enjoy worldly objects. He compares this to lighting a bulb not to eat the bulb, but to see the food clearly for consumption. This "second hope" or external expectation is what keeps individuals bound. True light should serve to negate the value of worldly objects by revealing their worthlessness, like showing that a perceived gold brick is actually rusted iron. However, the ego often uses even the highest knowledge as a tool to fulfill primitive, animalistic desires. He emphasizes that the purpose of light is to free one from the futile hope placed in objects, yet people often use it merely to search for more things to consume.
