Amid the scorching summer days, within the Daoist Field of the Beginningless, beside a lake, Gu An was preaching the Great Dao to his disciples, who were listening as if intoxicated.
Seeing that everyone had sunk into the enlightenment of the Dao, Gu An took out a jade flute from his bosom and admired it closely.
"Gu An, the Great Dao you speak of is truly profound and vast, conjuring in me numerous visions. However, I am very curious, have you actually seen those embodiments of the Great Dao?"
Shen Zhen opened her eyes, looked at Gu An, and asked curiously.
She was the closest to Gu An, and her voice was so soft that it did not disturb the others.
Gu An glanced at Shen Zhen and said, "The Great Dao is everywhere. What have you seen? Where do you wish to go?"
With a troubled look, Shen Zhen said, "I saw the universe and the stars, and a white staircase leading to a door."
"What kind of door?"
"Indescribable, all I can remember now is vague, but I'm sure it was a door."
