Ubuntu is a concept that traces its roots to Africa. It signifies the fact that no human is an island and cannot expect to grow isolated from rest of the society. We are a sum total of our ecosystem inclusive of the people who share this world with us.
This is a powerful concept and in someways a radical departure from the capitalistic approach that western world has consciously adopted. However, it is also equally important to note that the philosophy is not advocating a socialistic approach. All it does is to remind us that we cannot and should not forget the interconnected nature of humanity and even, nature. If we continue to choose the path of maximization of individual wealth while ignoring the plight of needs of those around us, these gains will be short lived. We might earn a short lived satisfaction of having more wealth or having won more accolades but true satisfaction in life comes when we have managed to take the society along with us on our journey.
Ubuntu preaches coexistence. Ubuntu advocates sharing and caring. Ubuntu teaches us to focus on gratitude. And makes us a better and more successful human being in the process.
