Single-sensed souls, however, called "nigoda", and element-bodied souls pervade all tiers of this universe. "Nigodas" are souls at the bottom end of the existential hierarchy. They are so tiny and undifferentiated, that they lack even individual bodies, living in colonies. According to Jain texts, this infinity of "nigodas" can also be found in plant tissues, root vegetables and animal bodies. Depending on its karma, a soul transmigrates and reincarnates within the scope of this cosmology of destinies. The four main destinies are further divided into sub-categories and still smaller sub–sub categories. In all, Jain texts speak of a cycle of 8.4 million birth destinies in which souls find themselves again and again as they cycle within "samsara".
