法華玄論 4.24

4.24

Answer: If the six perfections are equally non-attainment, they must rely on prajñā to become non-attainment; hence prajñā is the root and the other five perfections are the branches. The Pañcaviṃśati says: "When birds flock to Sumeru, they all share the same golden colour." Although they share the same golden colour, Sumeru is the root; it must be due to Sumeru that their colour becomes identical.
