According to Bhagavad Gita, one of the main instructions to life is to trust the process and focus on the process instead of the results.  I believe the core purpose of human life is to just exist. Some days are better than the others. Sometimes things may not go according to your plan, and that’s okay. If we don’t have bad days, how can we appreciate the good days?

So, the main purpose of human beings and mortality in general is to simply be. Sometimes just being there can create a huge shift in evolution. It doesn’t matter what you do or how you live, as long as you don’t give up. The universe will always look out for you if you look out for yourself.
