俱舍論頌疏論本 18.147

18.147

釋曰：說法無倒稱為如實，不求名利是無染心。若能如實以無染心辨契經等，令生正解，名為法施。

Explanation: Expounding the Dharma without error is called "in accordance with reality"; not seeking fame or gain is a "mind without defilement." If one can, in accordance with reality and with an undefiled mind, distinguish sūtras and so forth to cause right understanding to arise, this is called the gift of Dharma.
