維摩經略疏 8.69

8.69

問：云何言三乘皆是化他，一乘但是自行？答：三乘隨他意語，故一往對化他；一乘隨自意語，故一往對自行。究論，皆有自他。

Question: Why is it said that the three vehicles are entirely for transforming others, while the One Vehicle is only for one's own practice? Answer: The three vehicles are spoken in accordance with the intentions of others, and so provisionally correspond to transforming others; the One Vehicle is spoken in accordance with one's own intention, and so provisionally corresponds to one's own practice. In ultimate analysis, both contain self and other.
