Answer: The spiritual ascent consists of several parts: the development of the Universe, the evolution of Earth, and spiritual correction which began with the breaking of a part of humanity (the nation of Israel from the time of Babylon until the destruction of the Second Temple), the continuing development of humanity to our times, up to the beginning of the crisis between humanity and nature (the Creator).
Starting with this latter stage, the crisis, gradually all people will start feeling a need to rise above the level of our world and attain the purpose for the world’s existence and for everything that happens in it. This will bring them to the science of Kabbalah which was revealed back in Ancient Babylon.
Everything comes down to replacing our nature with an Upper one, to replacing egoism (the desire to receive for one’s own benefit) with altruism (the desire to bestow). This process occurs in stages, by attaining 125 degrees. However, a person goes through an initial period of preparation within the group, through the theoretical study of spiritual qualities, and by examining one’s egoistic nature. When, under the influence of that environment, a sufficiently powerful desire emerges in him to replace egoism with bestowal to others, the common force of nature, the Upper Light, will change him. Then one begins to experience worry (fear) about others, much like a mother does in relation to her child.
But this is still only an ascent above egoism. Subsequently, follows the stage of acquiring the quality of love where a person is willing to give everything to others as they become more dear to him than he is to himself. During this stage a person begins to feel and merge with the Creator because he becomes equal to Him through his actions.
