瑜伽師地論略纂 11.142

11.142

論解一切門中，語有四：第一、令入佛法，先說五停心觀，最先所應作法也；第二、已入法者；餘可知。

Where the treatise explains that speech in all gateways has four aspects: the first is causing [them] to enter the Buddha's Dharma, by first teaching the meditations of the fivefold stilling of the mind, which is the very first practice that should be done; the second is for those who have already entered the Dharma; the rest can be understood.
