法苑珠林 69.42

69.42

故三昧經云。說身內火界漸增水界漸微。是故迦羅邏稠漸堅。乃至肉團。眾生由此薄福。從小至大。皆受其苦。

Therefore, the Samādhi Sūtra says: It states that the fire element within the body gradually increases while the water element gradually diminishes. Therefore, the kalala gradually thickens and solidifies, until it becomes a lump of flesh. Sentient beings, due to their meager merit, endure suffering from small to great.
