Where from have you come from? Frog of the sea told that he has come from the sea or ocean which is very big. How big? asked the well-frog. Sea-frog said that it is so big that I cannot tell you. On hearing this well-frog jumped two steps in the well & asked whether sea is that much big. At this, sea-frog laughed loudly & told, no no, sea is very very big. Again the well-frog was puzzled & again jumped bigger steps in the well & asked whether sea is that much big. At this, once again the sea-frog laughed very loudly & told, no no, sea is very very big, it is so vast & big that I can't explain it to you in words. Now well-frog was unable to comprehend what the sea-frog was talking about. For the well-frog, his world was limited to that well only & so was his mind conditioned to that thinking that there is no world outside that well & nothing can be bigger than that well.
Same is applicable with human mind also. Now you just tell me, how big is this space in which so many stars & universes are there. Now if your mind thinks of a certain figure of distance & number of stars, then your mind is limiting itself to a certain boundary. But this vast existence is beyond the boundaries because beyond the boundary, again starts another sky which is limitless & is having so many stars & universes. So in the flight of the mind skies upon skies are there in this vast space.
"Sitaron Ke Aagey Jahan Aur Bhi Hain"
There are more & more Worlds beyond these Stars.
In fact this whole vast creation is limitless & infinite. It is beyond the conception & boundaries of human mind. As per the Bhagwat Gita, this whole universe, in which Supersoul or Brahmn resides is Limitless (Anant). This whole vastness of this universe or space cannot be comprehended by the limited human mind. Human mind always thinks within the boundaries. This limited thinking of human mind limits itself to think about the true vastness of one's own true self, which is unlimited in potential. One can always attain much more in life than what his/her limited mind thinks of attaining. So do not be content easily in life & always strive to achieve more & more in life. You are capable of doing & achieving much more in life than what your limited mind can imagine. Those who remain content easily in life always remain small in life; small are their joys, small are their happiness, small is their being. If you are one among such content people then this smallness is your own imposition upon your unlimited possibilities, upon your freedom, upon your unlimited potential.
