Answer: It is from the moment that a person feels that the Creator has awakened him to connect with Him.
It begins from a state, which is called, as it is written, “You hid Your countenance and I became frightened” (Psalms 30:8). That is how the work of the Creator with a person begins. It is a state in which the Creator draws a person toward Him by arousing fear in him. The person must immediately invest effort at every moment to reveal the Creator within him until the person reaches a state in which he is ready for anything to get away from himself and seemingly doesn’t exist. The main thing is to feel the Creator and feel that he is giving Him contentment by this.
