The mind is impotent, incapable of knowing the beginningless and the endless. The mind exists between birth and death; it knows nothing beyond birth and beyond death.
You were here before you were born, and you will be here after you are dead. The mind has a very limited existence, very momentary -- one day it comes, another day it is gone.
You are forever. Have some experience of your forever-ness.
But that is possible only through no-mind. No-mind is another name for meditation.
