Sanskrit and the Yoga Sutras: Certainty of Freedom

In Sanskrit the concept of spiritual freedom exists as a certainty. It exists within the context of an ancient proven science, equally precise as our modern science which has managed to send human beings into outer space and have them actually walk on the moon. For modern science to accomplish that extraordinary feat, there had to first exist the certainty that it was possible. For this to even be considered, there had to be an already existing language, that could gauge the precise requirements to get a vehicle beyond the gravitational field of the earth, find the moon, land, and return.
