Punarbhava or rebirth really suggests the constant conversion of the one into bhava or continuous existential diversity which we, as human beings, experience as ‘birth and death’. To understand this more fully, it is important to keep in mind that the universe is constituted of one medium (a singular light) which is capable of infinite self-modification or the same, infinite diversification. For those undergoing rebirth, this conversion process is both mysterious and perplexing since the one medium leaves no trace of its unmodified nature in the process of diversifying itself.
