Everyone who has understood the fundamentals of evolution has the responsibility to transmit his knowledge to some others. In this, the one who transmits the knowledge, whether he is great or not, is subject to the same law: he must pass his knowledge on without violating the freedom of others. The fundamentals of evolution can be realized only voluntarily, and can be applied in life only through the striving of the awakening spirit.
One must rebuild one’s entire life for the new step in evolution. This is impossible for one who is not ready to offer himself in spirit to earthly service. In fact, this offering is of the greatest importance for the completion of one’s earthly path. From the most ancient precepts of Vedanta We know of this principle of liberation. Facing this new step of evolution, it is Our duty to repeat again and again about this propelling force. (AY (opens in new tab), 153)
