法華義疏 11.192

11.192

從經初至〈囑累品〉明佛所乘法、能乘人究竟，故大眾歡喜。下〈藥王品〉乃明菩薩所乘法、能乘之人，故〈囑累品〉在中間也。

From the beginning of the sūtra to the "Entrustment Chapter," it explains that the Dharma ridden by the Buddha and the person capable of riding it are consummate; therefore the great assembly rejoices. Below, the "Bhaiṣajyarāja Chapter" explains the Dharma ridden by bodhisattvas and the persons capable of riding it, which is why the "Entrustment Chapter" stands in the middle.
