首楞嚴義疏注經 8.577

8.577

「於己妻房婬愛微薄，於淨居時不得全味，命終之後超日月明，居人間頂。如是一類名忉利天。」

"Those whose lust and affection toward their own wives are faint, and who do not obtain full savor during pure cohabitation, after the end of their lives transcend the radiance of the sun and moon and dwell atop the human world. Such a category is called the Trāyastriṃśa Heaven."
