成唯識論了義燈 5.106

5.106

答：本《疏》已引文，又《出曜論》〈念品〉中說：昔佛在時有空界天，名歡樂過，猶極歡樂。從彼沒故來生此間，從喜噬天。文亦同此，既言空界天，明非地居。

Answer: The root commentary has already cited the text. Furthermore, the 'Mindfulness Chapter' of the Avadāna-śāstra states: 'In the past, when the Buddha was in the world, there was a space-dwelling deva named Excessively Joyful, who was extremely joyful. Dying from there, he came to be born here, from the Krīḍāpradūṣika devas.' The text is also the same as this. Since it says 'space-dwelling deva,' it clearly is not earth-dwelling.
