There is a changeless reality beneath the world of change.
The scriptures of Vedanta are saying: "In the early part of the first millennium B.C. we find stated both the methods and the discoveries of brahmavidya (knowledge of the absolute) With this introspective tool the inspired rishis (literally “seers”) of ancient India, analyzed their awareness of human experience to see if there was anything in it that was absolute. Anything that doesn't change. Their findings can be summarized in three statements: (1) there is an infinite, changeless reality beneath the world of change; (2) this same reality lies at the core of every human personality; (3) the purpose of life is to discover this reality experientially: that is, to realize God while here on earth. These principles and the interior experiments for realizing them were taught systematically in “forest academies” or ashrams – a tradition which continues unbroken after some three thousand years."
