The Self is eternal and so are the Vedas, which proclaim the Existence, the Knowledge, and the Bliss of it. Worlds and their cycles come and go, like passing shows on the screen without any progressive improvement or otherwise. They are as they are, ever. The Self IS! Being timeless, no 'ever' can qualify It — One's very SELF! Attention! No science of matter or numbers or logic can ever reveal it. Being within, it needs to be found by a meticulous pursuit involving one's mind introverted by enquiry and a source of thorough quest of the mind ripened by unsullied and relentless self-discipline. *Source:* Shri Ribhu Gita (2.67), translated by Dr Lingeswara Rao and Dr Anil Sharma
