　　Since an uncontrolled response to the sensory input stimulates the latent defilements, what is evidently needed to prevent them from arising is control over the senses. Thus the Buddha teaches, as the discipline for keeping the hindrances in check, an exercise called the restraint of the sense faculties (indriya-samvara):

　　When he perceives a form with the eye, a sound with the ear, an odor with the nose, a taste with the tongue, an impression with the body, or an object with the mind, he apprehends neither the sign nor the particulars. And he strives to ward off that through which evil and unwholesome states, greed and sorrow, would arise, if he remained with unguarded senses; and he watches over his senses, restrains his senses.[40]

　　Restraint of the senses does not mean denial of the senses, retreating into a total withdrawal from the sensory world. This is impossible, and even if it could be achieved, the real problem would still not be solved; for the defilements lie in the mind, not in the sense organs or objects. The key to sense control is indicated by the phrase "not apprehending the sign or the particulars." The "sign" (nimitta) is the object”s general appearance insofar as this appearance is grasped as the basis for defiled thoughts; the "particulars" (anubyanjana) are its less conspicuous features. If sense control is lacking, the mind roams recklessly over the sense fields. First it grasps the sign, which sets the defilements into motion, then it explores the particulars, which permits them to multiply and thrive.

　　To restrain the senses requires that mindfulness and clear understanding be applied to the encounter with the sense fields. Sense consciousness occurs in a series, as a sequence of momentary cognitive acts each having its own special task. The initial stages in the series occur as automatic functions: first the mind adverts to the object, then apprehends it, then admits the percept, examines it, and identifies it. Immediately following the identification a space opens up in which there occurs a free evaluation of the object leading to the choice of a response. When mindfulness is absent the latent defilements, pushing for an opportunity to emerge, will motivate a wrong consideration. One will grasp the sign of the object, explore its details, and thereby give the defilements their opportunity: on account of greed one will become fascinated by an agreeable object, on account of aversion one will be repelled by a disagreeable object. But when one applies mindfulness to the sensory encounter, one nips the cognitive process in the bud before it can evolve into the stages that stimulate the dormant taints. Mindfulness holds the hindrances in check by keeping the mind at the level of what is sensed. It rivets awareness on the given, preventing the mind from embellishing the datum with ideas born of greed, aversion, and delusion. Then, with this lucent awareness as a guide, the mind can proceed to comprehend the object as it is, without being led astray.

　　(2) To abandon the arisen unwholesome states

　　Herein the disciple rouses his will to overcome the evil, unwholesome states that have already arisen and he makes effort, stirs up his energy, exerts his mind and strives.[41]

　　Despite the effort at sense control the defilements may still surface. They swell up from the depths of the mental continuum, from the buried strata of past accumulations, to congeal into unwholesome thoughts and emotions. When this happens a new kind of effort becomes necessary, the effort to abandon arisen unwholeso…
