Temporary enjoyments might be achieved by unbridled and indiscriminate engagement of the senses and unloyalty to the scriptures which preach self-discipline in all matters. As knowledge is to a dunce, so is the Self to the unchecked mind. Can air, which mediates smell, be a medium for light? Similarly, knowledge of matter such as the triad of qualities etc. cannot relieve one from bondage. Prajna or the pure intellect called 'I' is the medium for knowledge. Ceaseless pursuit of the I leads to illumination of the Self. *Source:* Shri Ribhu Gita (2.68), translated by Dr Lingeswara Rao and Dr Anil Sharma
