大般涅槃經集解 7.108

7.108

案僧亮曰：身雖多分，而性空無二，無二則無非我所惜也。僧宗曰：方便智易用，如右臂也。終聞常教，皆有受義，故言一切相與也。慧朗曰：右臂者，取一邊之義，譬偏教也。

Sengliang comments: Although the body has many parts, its nature of emptiness is non-dual; since it is non-dual, there is nothing that is not mine to spare. Sengzong says: Expedient wisdom is easy to employ, like a right arm. In the end, upon hearing the teaching of permanence, they will all receive it, so it is said that 'I will give you everything'. Huilang says: The 'right arm' takes the meaning of one side, symbolizing the partial teaching.
