Chapter 2 in the Gita, towards the end, talks of dwandvas, which refers to duality, like two sides of the same coin. This duality is such, that no matter what the situation, the other side will occur as well – whether we like it or not. Life is full of such dwandvas. Night is always followed by day, and day by night. This can never be changed. Pain is followed by pleasure, and pleasure by pain. There is no escaping it. Success is followed by failure, and that failure in turn can lead to great success. Where great joy exists, great pain will follow too.
There are literally countless examples – pretty much everything we see and feel around us. Get too close to somebody? Then the pain of separation will eventually become too much. Love your child too much? One day s/he will have to go away for higher education or marry someone elsewhere. Love your job or role or credentials? One day you will have to retire and all these will become meaningless. Desperately waiting to go on a vacation? Soon the vacation will come to an end and you will be back at work. And thus the cycle continues, on and on and on.
What’s the point of thinking this way? Only to understand and appreciate that this duality is the nature of the world around us. We keep praying to God for many things. Each of those things also comes with the same duality only. We pray for good things to happen to us. But we forget that these good things will by design come with some not-so-good stuff attached. That is the law of life and creation. So if a prayer isn’t answered, maybe we shouldn’t be depressed about it after all?
In any case, there is only one thing that is non-dual. And that singular omnipotent omnipresent omniscient being can be found deep within each one of us.
