Causal Condition, known as Īsvara. While the wakingconsciousness, individually, is called Viśva, it is calledtaijasa in dream, and prājña in the deep sleep state.Correspondingly, from the cosmic level, we have Virāt inwaking, Hiraṇyagarbha in dreaming, and Īsvara in deepsleep. While we, ordinarily, hold that the impressions ofwaking create dream and an adjournment of all theactivities of these impressions is sleep, thus deducing dreamfrom waking and sleep from both, in the cosmic level wecannot make such deductions, because a reverse processtakes place there which seems to be a prior condition to theindividual state. Īsvara being the cause of Hiraṇyagarbha,and Hiraṇyagarbha being the cause of Virāt. Therelationship between the individual and the cosmic,between Viśva and Virāt, taijasa and Hiraṇyagarbha, prājñaand Īsvara is one of organic integrality, and a realisation ofthis organic connection of being will land the jīva inĪsvaratva and make it at once omnipresent, omniscient andomnipotent.91
