Vedanta is not intellectual acrobatics. You can study all the scriptures and know them by heart. But, unless the quality of mind improves, one cannot find the truth.
And how does the quality improve? It’s by understanding that one is not in control. It’s simple to understand. When we are infants, we are helpless. To go to the other room, somebody has to lift us and carry there. We can’t even go to the toilet on our own. We can’t eat; somebody has to feed us. When we become old, helpless and fall sick and die, again the same thing happens.
In between, there is a period in our life, when we really think that we are in control. We are not in control. If we realize this, then we have surrendered.
