Right Understanding, which is the key-note of Buddhism, is explained as the knowledge of the four Noble Truths. To understand rightly means to understand things as they really are and not as they appear to be. This refers primarily to a correct understanding of oneself, because, as the Rohitassa Sutta states, "Dependent on this one-fathom long body with its consciousness" are all the four Truths. In the practice of the Noble Eightfold Path, Right Understanding stands at the beginning as well as at its end. A minimum degree of Right Understanding is necessary at the very beginning because it gives the right motivations to the other seven factors of the Path and gives to them correct direction. At the culmination of the practice, Right Understanding has matured into perfect Insight Wisdom (vipassana-pañña), leading directly to the Stages of Sainthood.

As long as this Kammic force exists there is re-birth, for beings are merely the visible manifestation of this invisible Kammic force. Death is nothing but the temporary end of this temporary phenomenon. It is not the complete annihilation of this so-called being. The organic life has ceased, but the Kammic force which hitherto actuated it has not been destroyed. As the Kammic force remains entirely undisturbed by the disintegration of the fleeting body, the passing away of the present dying thought-moment only conditions a fresh consciousness in another birth. It is Kamma, rooted in ignorance and craving, that conditions rebirth. Past Kamma conditions the present birth; and present Kamma, in combination with past Kamma, conditions the future.

According to Buddhism mind is nothing but a complex compound of fleeting mental states. One unit of consciousness consists of three phases — arising or genesis (uppada) static or development (thiti), and cessation or dissolution (bhanga). Immediately after the cessation stage of a thought moment there occurs the genesis stage of the subsequent thought-moment. Each momentary consciousness of this ever-changing life-process, on passing away, transmits its whole energy, all the indelibly recorded impressions to its successor. Every fresh consciousness consists of the potentialities of its predecessors together with something more. There is therefore, a continuous flow of consciousness like a stream without any interruption. The subsequent thought moment is neither absolutely the same as its predecessor — since that which goes to make it up is not identical — nor entirely another — being the same continuity of Kamma energy. Here there is no identical being but there is an identity in process. Every moment there is birth, every moment there is death. The arising of one thought-moment means the passing away of another thought-moment and vice versa. In the course of one life-time there is momentary rebirth without a soul. It must not be understood that a consciousness is chopped up in bits and joined together like a train or a chain. But, on the contrary, "it persistently flows on like a river receiving from the tributary streams of sense constant accretions to its flood, and ever dispensing to the world without the thought-stuff it has gathered by the way."
