[Er.sandeep jain]

Perfect-knowledge – omniscience (kevalajñāna) – passes through all objects, and perfect-perception (kevaladarśana) extends over the universe (loka) and the non-universe (aloka). On destruction of ignorance, the cause of misery, must arise the knowledge, the cause of happiness.

Explanatory Note: Anything that impinges on the nature of the soul is misery, and destruction of misery is happiness. The knowledge (jñāna) and the perception (darśana) constitute the nature of the soul. So long as the causes of envelopment of the nature of the soul are present, it does not enjoy the freedom to know and see all objects. This is misery for the soul. On destruction of the causes of its envelopment, the soul knows and sees everything. This ability of the soul is unhindered happiness, independent of all outside intervention. Therefore, perfect knowledge (kevalajñāna) and perfect-perception (kevala darśana) are the causes of happiness. Perfect-knowledge is the happiness of the soul; therefore, perfect-knowledge is happiness. In perfect knowledge (omniscience), ignorance, the cause of misery, is destroyed and knowledge, the cause of happiness, is attained. In 
essence, perfect-knowledge (kevalajñāna) is happiness.
