All water of ocean is connected. There are no barriers. no boundaries and no separations among them. We have named them with nearby pieces of land/ continents/ islands etc for the purpose of identifying them as Indian Ocean. Atlantic Ocean (North and South), Pacific Ocean (North and South) etc.
All Seas are part of Ocean. Those bodies of water which separated from the seas and Oceans as a result of ever ongoing geological changes are no more seas though they are still known with their previous names. Thus Caspian Sea, Dead Sea are no more seas. They are just lakes. They are no more part of large body of water, the Ocean.
Knowledge is like Ocean. There must not be any barriers among different so called branches of Knowledge. It prospers and expands only if it is one, only when it is not separated. Specialisations and sub-specialisations are meaningless if they are not part and parcel of main Ocean of Knowledge.
Therefore one must maintain his freedom and independence to learn. When somebody fixes himself with some specific religious sect, religion, political party etc and stops looking around, his learning stops and ultimately ends with total death. One must follow the principles and must not affix himself with systems. If principles remain alive, they can evolve better and more better systems. Everything in the Universe is based on "movement and expansion".
