Shiva is considered supreme and beyond His creation and it is believed that souls shares with Him all those qualities He represents which are meant to be achieved through self-purification or asceticism as a tool for understanding and practicing the way of Bliss.
A: Asceticism or being yogi is the essence of human life
B: Bondages are materialistic and confine the soul to earthly existence and it may be saved through self-purification
C: Concept is to get rid of soul's materialistic bonds and gain shivatva or ?the nature of Shiva? or Bliss
D: Deeming Soul as an infinite, pervasive and omniscient, but due to its association with impurities or sense-objects bonds, it experience themselves as finite, limited and ignorant.
E: Endowment of the soul with a psycho-physical organism or body-mind combine and its dominance cause materialism or pursuit objects of sensual enjoyment leading to impurities.
Thus, according to Shaivism, the birth and world process is for the sake of the soul's release. Shiva remains the same whether the world evolves or not. In other words, Shaivism does not favour the doctrine of Avatara or incarnation of the Supreme. In a nutshell, the main tenet of shaivism is that remove your vices, the good will automatically be done.
