Nibbana of the Buddhists is neither a mere nothingness nor a state of annihilation, but what it is no words can adequately express. Nibbana is a Dham… - Narada Maha Thera

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."

Buddhism does not totally deny the existence of a personality in an empirical sense. It only attempts to show that it does not exist in an ultimate sense. The Buddhist philosophical term for an individual is Santana, i.e., a flux or a continuity. It includes the mental and physical elements as well. The Kammic force of each individual binds the elements together. This uninterrupted flux or continuity of psycho-physical phenomenon, which is conditioned by Kamma, and not limited only to the present life, but having its source in the beginningless past and its continuation in the future — is the Buddhist substitute for the permanent ego or the immortal soul of other religions.

Kamma, literally, means action; but, in its ultimate sense, it means the meritorious and demeritorious volition (Kusala Akusala Cetana). Kamma constitutes both good and evil. Good gets good. Evil gets evil. Like attracts like. This is the law of Kamma. As some Westerners prefer to say Kamma is "action-influence." We reap what we have sown. What we sow we reap somewhere or some when. In one sense we are the result of what we were; we will be the result of what we are. In another sense, we are not totally the result of what we were and we will not absolutely be the result of what we are. For instance, a criminal today may be a saint tomorrow. Buddhism attributes this variation to Kamma, but it does not assert that everything is due to Kamma. If everything were due to Kamma, a man must ever be bad, for it is his Kamma to be bad. One need not consult a physician to be cured of a disease, for if one's Kamma is such one will be cured. … Kamma is, therefore, only one of the five orders that prevail in the universe. It is a law in itself, but it does not thereby follow that there should be a law-giver. Ordinary laws of nature, like gravitation, need no law-giver. It operates in its own field without the intervention of an external independent ruling agency. Nobody, for instance, has decreed that fire should burn. Nobody has commanded that water should seek its own level. No scientist has ordered that water should consist of H2O, and that coldness should be one of its properties. These are their intrinsic characteristics. Kamma is neither fate nor predestination imposed upon us by some mysterious unknown power to which we must helplessly submit ourselves. It is one's own doing reacting on oneself, and so one has the possibility to divert the course of Kamma to some extent. How far one diverts it depends on oneself. … It should be stated that Kamma has both the continuative and the retributive principle. Inherent in Kamma is the potentiality of producing its due effect. The cause produces the effect; the effect explains the cause. Seed produces the fruit; the fruit explains the seed as both are inter-related. Even so Kamma and its effect are inter-related; "the effect already blooms in the cause."
