10.126

前中，言若諸菩薩於所行施意樂清淨乃至不應捨正現在前利眾生而施身分者，此中諸菩薩先來意樂清淨不捨己身，於現前中有利眾生事，設有來求生菩薩支節不應施與，以現前利益多故，捨利益少故，通多利益事行，若心退轉自生念言，此應可共不共心，生慳悋，惜己身故，為破悋故，須捨身分，先心已清淨不捨己身，現前後利益事多不應施身分，是此中意。

In the former, regarding the statement that if bodhisattvas have a pure intention in the giving they practice, up to not abandoning a currently manifest benefit to sentient beings to give away a bodily part: here, the bodhisattva's intention has been pure from the outset, not [arising from a selfish desire of] not abandoning their own body; and in the present there is an undertaking that benefits sentient beings. Even if someone comes begging for a bodily part of the living bodhisattva, it should not be given. Because the present benefit is greater, while the benefit of relinquishing [the body part] is smaller, [this principle] applies generally to undertakings that bring many benefits. If their mind backslides and the thought arises in them, 'This ought to be shared, but [I have] an unsharing mind,' generating stinginess and cherishing their own body, then in order to shatter that stinginess they must relinquish the bodily part. But if their mind was already pure from the outset and their not relinquishing their own body is because the present and subsequent benefits are greater, they should not give away a bodily part. This is the meaning here.
