In Kashmir Shaivism, there are three classifications of tattva: pure tattvas, pure-impure tattvas and impure tattvas. Kaala, together with power, knowledge, space and passion, belongs to the second group of the pure-impure tattvas, describing the soul and the limitations of the soul.
In Hinduism, kaala is sometimes personified as Yama because death ends one's time on Earth. The soul, however, has no time, no beginning or end; therefore, it cannot die. One must go beyond the limitations of time and the other 35 tattvas in order to achieve pure consciousness and liberation.
