維摩經略疏 3.17

3.17

From "Long since to the Great Vehicle": these three lines are the sixth, praising the long accumulation of cultivation and seeing principle clearly, like a worldly householder of advanced age and long experience. Therefore the Lotus Sūtra clarifies that Mañjuśrī had already long encountered buddhas, cultivating and learning for accumulated kalpas. This was also like that; hence it says "thoroughly seasoned." "Determined in the Great Vehicle" means seeing principle clearly and being able to make the lion's roar. The lion's roar means preaching that all sentient beings possess the Buddha-nature. As the Great Sūtra says, the Buddha-nature is precisely the Great Vehicle.
