The Long Āgama Sūtra 14.30

14.30

爾時，帝釋即白佛言：「實爾。世尊！貪嫉之生，皆由愛憎，愛憎為因，愛憎為緣，愛憎為首，從此而有，無此則無。我今聞佛所說，迷惑悉除，無復疑也。但不解愛憎復何由而生？何因何緣？誰為原首？從誰而有？從誰而無？」

Lord Śakra then said to the Buddha, “Indeed, it is, Bhagavān! The arising of greed and jealousy have their origin in love and hate. Love and hate are their causes and conditions. Love and hate are their source. From them, they come to exist. In their absence, they cease to exist. Now that I’ve heard the Buddha’s explanation, my confusion is completely removed. I won’t wonder about it anymore.

“But I don’t understand the arising of love and hate. What are their causes and conditions? What is their source? From what do they come to exist? From what do they cease to exist?”
