俱舍論疏 2.226

2.226

「論曰至眼等非餘」，如文可解。《正理論》云「若爾意識亦隨身轉，謂風病等損惱身時意識即亂，身清泰時意識安靜，何緣彼意識不以身為依？隨自所依，故無此失。謂風病等損惱身時，發生苦受相應身識，如是身識名亂意界。此與苦受俱落謝時，能為意根生亂意識。與此相違，意識安靜，是故意識隨自所依。豈不有漏意界無間無漏識生，如是等異，如何意識隨自所依？非據有漏、無漏等類名隨自所依，但據增損、明昧差別。如從無覆無記眼根，生善、不善有覆眼識，而名眼識隨自所依。此亦應爾，是故能依非隨一切所依法性。若不爾者，應非能依隨所依故。」

From the commentary's 'It says: [...]' up to 'the eye and so on, not others', this can be understood from the text. The Nyāyānusāra states: 'If so, then mental consciousness also fluctuates along with the physical body; that is, when wind diseases and the like afflict the body, mental consciousness is disordered, and when the body is at ease, mental consciousness is tranquil. For what reason does that mental consciousness not take the body as its basis? Because it fluctuates along with its own basis, there is no such fault. That is, when wind diseases and the like afflict the body, body-consciousness associated with painful feeling is generated; such a body-consciousness is called a disordered mind-element. When this passes away together with the painful feeling, it is capable of serving as a mind faculty that generates a disordered mental consciousness. In contrast to this, mental consciousness is tranquil; therefore, mental consciousness fluctuates along with its own basis. Does not an uncontaminated consciousness arise immediately following a contaminated mind element? With such differences, how does mental consciousness fluctuate along with its own basis? It is not according to categories such as contaminated or uncontaminated that it is said to fluctuate along with its own basis, but merely according to distinctions of deterioration or improvement, clarity or dullness. Just as from an eye faculty that is non-obscured and neutral, a wholesome, unwholesome, or obscured eye-consciousness is generated, and yet it is called eye-consciousness fluctuating along with its own basis. This should also be the case here; therefore, that which relies does not fluctuate along with all phenomenal characteristics of what is relied upon. If it were not so, then that which relies would not fluctuate along with what is relied upon.'
