Previously, we learned about the process of cosmic creation, where all the living and non-living beings in the universe become manifest at the beginning of the day of Brahma. Now, Shri Krishna elaborates on the dissolution aspect. He says that all those beings go into an unmanifest or “frozen” state during the night of Lord Brahma. The very same beings become manifest or “un-frozen” again, when the day of Lord Brahma begins.
As we saw earlier, nothing is ever created or destroyed. The very same set of beings becomes manifest and unmanifest. The total number of “beings” in the universe remains the same. Those who die are “born” into a different form. Forms change but the total amount of universal “stuff” remains the same. It is said that there are 8.4 million species, which are nothing but forms. The movie ends, the reel is rewound, and it begins all over again, on and on, without any end in sight.
Now, here is one word in this shloka that deserves further attention. It is “avashaha” which means helplessly. Shri Krishna says that all beings, even if they are plants, animals, minerals or humans are helplessly stuck in this wheel of birth and rebirth, otherwise known as the wheel of samsaara. If they do not actively pursue a spiritual path, whatever that path may be, they will never come out of this cycle.
Most of us get frustrated if we get stuck in an elevator for more than a few minutes. Imagine how frustrated we should get if we find out that we are stuck somewhere for an infinite amount of time. So how exactly do we escape from this situation? We shall see in the next shloka.
