In this episode of Kathopanishad, we are emphatically urged to seek the truth right now as one never knows how long is left of their life. Learning this supreme truth is practically impossible on any other plane of existence, so we are warned not to wait for later or our next birth, but to make use of this one whilst we have it.

The future is uncertain and the past is already gone. The present moment is all that exists, so we should make the most of this precious opportunity and free ourselves from all illusion and suffering whilst we have this human body to do it with.
