The entire spiritual world. This phrase basically, covers everything related to spirituality, which takes a soul to the heights of the spiritual world – Param Padvi. The 7 LOK (body worlds) are the Sat Sarovars of spiritual energy within our body. The 7 PARLOK (higher realms) are the seven ascending realms of Truth the soul enters once in Samadhi due to the 7 LOK being activated. When our conscious travels through these realms of Truth (PARLOK) then we become knowledgeable about that particular realm of Truth. We develop an understanding of whatever happens in that particular realm. By the time we reach the seventh realm of Truth we have achieved everything and our brain becomes fully active.
