修習止觀坐禪法要 1.117

1.117

二、耳聞聲時修止者。隨所聞聲，即知聲如響相。若聞順情之聲，不起愛心；違情之聲，不起瞋心；非違非順之聲，不起分別心；是名修止。云何聞聲中修觀？應作是念：「隨所聞聲，空無所有，但從根塵和合，生於耳識；次意識生，強起分別。因此即有一切煩惱善惡等法，故名聞聲。」反觀聞聲之心，不見相貌。當知聞者及一切法，畢竟空寂，是名為觀。

Second, cultivating calming when the ear hears sounds: Whatever sound is heard, one immediately knows the sound is like an echo. If hearing agreeable sounds, one does not give rise to love; if hearing disagreeable sounds, one does not give rise to anger; if hearing sounds that are neither disagreeable nor agreeable, one does not give rise to a discriminating mind. This is called cultivating calming. How does one cultivate contemplation while hearing sounds? One should think thus: "Whatever sound is heard is empty and non-existent; merely from the conjunction of faculty and object, ear consciousness arises; next, mental consciousness arises, forcefully generating discrimination. Because of this, there are all defilements, wholesome, unwholesome, and other phenomena; therefore it is termed hearing sounds." Reflexively contemplating the mind that hears sounds, one sees no appearance [of it]. One should know that the hearer and all phenomena are ultimately empty and tranquil. This is called contemplation.
