The first verse of the Vedanta-sutras states: “athato brahma-jijnasa”, which means, “Now is the time to inquire about the Absolute Truth.” Why is it time? Because we are presently in the human form of life and should utilize it properly since only in the human form do we have the intelligence and facility to be able to understand spiritual reality. In animal forms, the living entities cannot understand such things because they do not have the brainpower. So we should not waste this human form of life by pursuing only the animalistic propensities, such as eating, sleeping, mating and defending. Therefore, the Vedanta-sutras begin by stating that now is the time for us to understand the Absolute Truth.
