What do we mean by attachment and object of attachment? As an example, when the eye consciousness perceives an object, attachment is formed. The object of attachment is that which is perceived by the eye consciousness. The eye consciousness and the object, that is, the attachment and the object of attachment, are separately known as the grasper and the grasped.
A pure or uncontaminated state is one in which grasper and the grasped all disappear; it is also the meditative state of bodhisattvas of the first and higher stages. Apart from the state of the buddhas and that of the realized bodhisattvas, all other states that contain grasper and the grasped are deemed impure or contaminated.
