Human beings waste their lives in stupid, vulgar activities, in passions and volcanic eruptions, without realizing that they are losing something irreplaceable. They imagine that life is eternal and abundant, that they can do whatever they please, and that it will always be available to them.
They are astonished, of course, when they find themselves completely exhausted. They have done everything to bring this about, yet they are still surprised and complain.
The least they could do is stop complaining, and say, ‘Well, what do you expect, we’ve experienced life, and now we see where the truth lies.’ But you, who have received the light of this Teaching, be vigilant, do not waste your life. Listen to the words of the song by Master Peter Deunov, ‘Sine moi, pazi jivota: My son, treasure your life, the spark buried within you, a precious gift.’ If there is one essential science that human beings need, it is this: to know how to preserve their lives and spend it in the service of heaven.
