Cosmic day and cosmic night

Just as the day dawns and gives way to night, all of creation arises in its infinite variety out of the unmanifested state and naturally merges back into the oneness of the unmanifest. The cosmic day dawns with its creation and lasts for thousands of ages before the cosmic night sees everything dissolve into oneness for thousands of ages as well. This cycle repeats itself as the oneness remanifests as separate forms again at the dawn of another cosmic day. Beyond these manifested and unmanifested states of phenominal existence is the truly unmanifested reality which exists eternally and remains untouched by these cycles of creation and dissolution. Experiencing this unmanifested state of reality which is infinite and indestructible is the ultimate goal of life. Those who attain this highest state never return to normal life in the world.
