Is there another lesson for us from what Swami Vivekananda did?
Do we completely give up our prayers, and wish for nothing?
And if we stop asking, will the Gods not make those things happen?
Do things happen only because we ask? Well surely this we know is not true. Our efforts matter, but most things are outside our control.
Then why pray? For our mental peace, at the very least. Because that is truly the only thing that matters. If we are lucky, specific chants might provide specific material results too.
Therefore it makes sense to pray for us to have the right mindset for every situation. That will us to samatvam, or equipoise in the face of everything.
