Buddhism teaches that there is a finite, but uncountable number of individual persons and of mental continuums. An individual person is something imputed on an individual mental continuum, much like a habit can be imputed on a continuum of repeated forms of similar behavior.The continuity of each individual person, like the continuity of each individual mental continuum, is eternal, but non-static. These continuities are eternal, in the sense of having no beginning and no end. However, they are non-static in the sense of changing from moment to moment.
In each moment, each person does something different, such as cognizing a different object.While under the influence of naivety, each person commits karmic actions and bears responsibility for those actions. The karmic legacies of these actions ripen into the person’s experience of samsaric happiness or suffering through a continuity of rebirths.
When a person is able to maintain continuous correct awareness of reality, the person becomes liberated from ever experiencing the ripening of these legacies. In this way, the continuity of the samsaric existence of that person ceases forever and the person attains liberation, nirvana.
Nevertheless, the ever-changing continuity of that individual person and of the mental continuum on which that individual person is imputed, go on eternally, even after the attainment of nirvana.In short, according to Mahayana Buddhism, the Buddhist branch to which Kalachakra belongs, an individual person is not permanent in the sense of being static; nor is an individual person impermanent in the sense of being temporary. Moreover, the samsaric existence of an individual person is not permanent in the sense of being eternal; nor is the nirvanic existence of an individual person impermanent in the sense of being temporary.
