In the phase zero of our existence, we remain governed by our instincts. That is how most animals and other lower level beings exist. In the next level, we evolve to use these instincts to our advantage and that of our companions. But that only ensured our existence but cannot take us further.
To move further, we need to evolve intellectually. And that is where our scientific evolution stands. But mere scientific progress is not sufficient. We need to evolve further by tempering science with morality, ethicality and compassion; that is aimed not just around us and our companions, but towards the entire universe. We need to move from ‘I’ to ‘We’.
But that is not all. The ultimate stage of evolution is to convert this ‘We’ into once again ‘I’, the ‘I’ this time is broadened in its scope encompassing the entire universe. It is the universal identity. We need to identify ourselves with the entire universe.
As ancient Indian Upanishads ask “when the ‘I’ expands to cover the entire universe, how can anyone harm anyone else, how can anyone be afraid of anyone else? It is then; there is no ‘anyone else’ but just ‘ME’”. That is the highest level of evolution.
But this evolution probably does not happen in one step. If you want to move from New York to New Delhi, you probably need to drive to the airport, take an international flight, probably make a couple of stopovers and finally reach New Delhi. Each mode of communication is important, but none of them are ultimate. You only use them to move further. It is only the destination that is the ultimate.
