召句曲山道士朱自英詣闕。賜號觀妙先生。初真宗以儲嗣久虛。命朱自英奏章升神帝闕。見三茅真君乘寶輦而下。問何所來。答曰。臣為大宋祈嗣。茅君頷之。以其章進太上。勅曰。茅盈憂國愛民。宜為宋嗣。明年仁宗生（句曲洞天在閏州句容縣。三茅君治此山長茅盈二弟固[褒-保+(罩-卓)]。詳見通塞志一卷）。

The Daoist Zhu Ziying of Mount Juqu was summoned to the imperial palace and granted the title 'Master of Contemplating the Wondrous'. Earlier, because the succession to the throne had long been vacant, Emperor Zhenzong ordered Zhu Ziying to present a memorial ascending spiritually to the Heavenly Emperor's palace. He saw the Three True Lords Mao descending in a jewelled carriage. They asked where he had come from, and he replied, 'Your servant is praying for an heir for the Great Song.' Lord Mao nodded, and presented his memorial to the Supreme Venerable. An imperial decree said: 'Mao Ying worries for the state and loves the people; he should become the Song heir.' The next year, Emperor Renzong was born (the Juqu Grotto-Heaven is in Jurong County of Runzhou. The Three Lords Mao rule this mountain: the eldest Mao Ying, and his two younger brothers Gu and Zhong. For details, see the Treatise on the Prosperity and Decline of the Dharma, Fascicle 1).
