瑜伽論記 15.408

15.408

解云：體雖不殊而義恒異，如前眼生後眼，有種子義邊，是其界義。令後生長邊，是其處義。說據同時根塵生識邊有二義，如眼根色塵唯生眼識，不生餘識，是則眼色望彼眼識有種子義。就增上緣說名種子，如前眼生後眼亦據增上緣中以說種子。若同時根塵生長識邊即是處義，故下論云處是何義，諸心心所生長門義。

Explanation: Although their substance does not differ, their meaning is constantly distinct. For example, when a prior eye generates a posterior eye, the aspect of having the meaning of a seed is its meaning of 'element'; the aspect of causing the posterior to grow and develop is its meaning of 'āyatana'. When spoken of regarding the simultaneous faculties and objects producing consciousness, there are two meanings: for instance, the eye faculty and form object generate only the visual consciousness and do not generate other consciousnesses; thus the eye and form, in relation to that visual consciousness, have the meaning of a seed. Speaking in terms of the dominant condition, this is called a seed, just as a prior eye generating a posterior eye is also spoken of as a seed within the dominant condition. If it is the aspect of simultaneous faculties and objects generating and developing consciousness, that is the meaning of āyatana; therefore, the treatise below says: 'What is the meaning of āyatana? It means the door for the arising and growth of all minds and mental factors.'
