觀無量壽佛經義疏 2.42

2.42

"'Now, casting the five limbs to the ground before the World-Honoured One, I beseech your compassion and repent; I only pray that the Sun of the Buddha will teach me how to contemplate a place of pure karma.'" The head and four limbs are the five limbs; since the five places are all round, they are also called the five wheels. Touching the ground is the most solemn of reverences. It is because of past sins that one experiences this suffering; now wishing to feel revulsion and abandon it, one must seek repentance. In Sanskrit it is kṣama, translated here as repenting past [wrongs]. Saying "chanhui" here presents both Chinese and Sanskrit together. Some say: chan means severing what follows, and hui means feeling shame for what came before. The Tathāgata's preaching of the Dharma breaks through obstacles and dispels doubts, like the sun illuminating the world, hence he is called the Sun of the Buddha. The environment and inhabitants of Sukhāvatī are all jointly formed by the pure karma of the principal and accompanying [beings], hence it is called a "place of pure karma." According to this, Vaidehī was directly seeking the contemplation method, hence she said, "teach me how to contemplate." Second, the main body of the sūtra.
