瑜伽論記 3.155

3.155

依觸緣受，發起於愛者愛支；由受用境廣起追求等者，是取支；由事業門者，所謂淨行事王等；利養門者，謂坐收種耕田等，此二外欲境起名欲求；或由戒禁門者，謂邪願戒禁取，由此起內身求，求當來樂果身故；或由解脫門者謂見取，由此起邪解脫求。有義：事業門謂欲取，利養門謂見取為利養故其執見勝，戒禁門者謂戒禁取，解脫門者謂我語取，諦故住故執我自性為解脫故。因此四取發起三求：一、欲求多求五欲故；二、內身求即有求求自體故；三、邪解脫求即邪梵行求求邪解脫故。如是求時，令先所起煩惱及業等者，謂業是有支，無明為發業，緣令當果生，無明非是有支。

Regarding 'relying on contact conditioning feeling, giving rise to craving,' this is the limb of craving. 'Due to experiencing objects, extensively giving rise to pursuit,' and so on, this is the limb of grasping. 'Through the gateway of enterprises' refers to pure conduct, serving the king, and so on; 'through the gateway of gain' refers to sitting to harvest seeds, plowing fields, and so on. These two arise from external desirable objects and are called the pursuit of desires. 'Or through the gateway of rules and observances' refers to the grasping of rules and observances through wrong aspirations; through this, one gives rise to the pursuit of the internal body, because one seeks a body of future pleasurable fruition. 'Or through the gateway of liberation' refers to the grasping of views; through this, one gives rise to the pursuit of wrong liberation. One opinion holds: the gateway of enterprises refers to grasping at desires; the gateway of gain refers to grasping at views, because for the sake of gain one's clinging to views is strong; the gateway of rules and observances refers to grasping at rules and observances; the gateway of liberation refers to grasping at the theory of self, because due to truth and permanence one grasps the self-nature of the self as liberation. Relying on these four grasps, three pursuits are initiated: first, the pursuit of desires, because one mostly seeks the five desires; second, the pursuit of the internal body, which is the pursuit of existence, because one seeks one's own substance; third, the pursuit of wrong liberation, which is the pursuit of wrong religious practice (brahmacarya), because one seeks wrong liberation. Regarding 'when seeking in this way, causing previously arisen afflictions and karma' and so on: this means karma is the limb of existence; ignorance serves as the condition that initiates karma, causing future fruitions to arise, but ignorance is not the limb of existence.
