5.419

云何泉謂六觸處者，六處如泉，煩惱如水，泉所出故。或安受受所攝者，基公解云：安受謂喜，受所攝謂樂。又以悅心名安適身名受所攝，不安返此，更有一解，安受謂喜樂，受所攝謂身心也，或受種子也。

'How can the six contact spheres be called a spring?': the six spheres are like a spring, and the defilements are like water, as they issue forth from the spring. Alternatively, regarding 'experiencing peacefully and that which is subsumed under feeling': Master Ji explains that 'peaceful experiencing' refers to joy, and 'subsumed under feeling' refers to bliss. Moreover, pleasing the mind is called peaceful, and comforting the body is called subsumed under feeling; unpeaceful is the opposite of this. There is yet another explanation: 'peaceful experiencing' refers to joy and bliss, and 'subsumed under feeling' refers to body and mind, or to seeds of feeling.
