I believe that if humanity is ever going to get it right and create a world of peace, justice, liberty, and abundance for all, humanity needs to understand who each one of us is, that is, we must move from the belief that it is our individuation, i.e. the ego or personality that is who we are, to a more profound and accurate comprehension which is that not only are we individuated, but at the same time we are all a part of the tree of life, and in particular, the branch of homo sapiens. This is easy to see from this metaphor: How foolish it would be if a leaf had consciousness and believed it was only a leaf without realizing that it is also a part of a tree.
Once this realization saturates humanity, it will be much more difficult for everyone to accept the current atrocities that beset humanity every day such as starvation, war, propaganda, poverty, etc. and much more likely to create a more beautiful world that resides inside of everyone´s heart.
Unconditional love for everyone is not very difficult. One only needs to love the divine that abides within all living beings and at the same time abhore all asocial, cruel, and dishonest behavior. Simply separate the action from the purity that may be buried or hidden, but that is inevitably within each of us.
