You would like to be free from the shackles of limitation of every kind. This attainment is called Moksha, Liberation. Freedom from every kind of limitation or finitude is Moksha . It is not just some achievement. There should be no mistake in this regard.
People are silly and childlike in thinking that it is for the peace of mind.
They understand nothing, really. You would like to become as wide as the world itself, and you would like to see everything in the world. You would like to know all things and be and know everything for all time to come. This is possible only if you can defy the limitation of space and the limitation of time. The Infinite alone can be considered as utter Perfection, where every kind of finitude is abolished.
