"Human beings waste their energy every day with so many useless, petty and coarse concerns and activities. They do not see that they are in the process of losing an irreplaceable treasure. They imagine that life is eternal and inexhaustible, that they can do whatever they like and it will always be at their disposal. They are surprised, of course, when they find themselves completely exhausted. They have done everything to bring this about, yet they are astonished and complain. The least they could do is stop complaining and acknowledge: ‘There, I have carried out some experiments, and I now realise where the truth lies.'

And you who receive the light of this teaching, be vigilant, do not waste your life. Protect it as the song by Master Peter Deunov says: ‘Sine moï, pazi jivota: My son, protect your life, that spark and precious gift buried within you.' If you are in need of science, the one true science is simply this: know how to preserve your life so you may consecrate it to the service of God."
