Very interesting read.
Translations and the long periods that elapsed in the cultures before being translated makes it really difficult to get the exact concept envisaged by the Buddha.
And purpose of language is only depict a feeling or material that was in existence before language evolved. And again the use of language is complicated only in human beings as they are sentient and percieve things.
Animals use language to do the communication for their needs and are pretty smart in the same. We human beings keep wondering what else animals think about and they are always in the moment enjoying every bit of living or existence. You can not find any deer ruminating the fear of the chase the leopard had a few hours ago and the fear with which it ran to save itself or that another deer in its herd had fallen prey. The deer just exists and is in the moment.
Taking the analogy forward there is only being in their life and that is fulfilling. Homo Sapiens are sentient and so can perceive and create their own reality. That is a boon and if not used properly a bane.
Dukkha that you have mentioned in your article is another human construct among many others and a nonexistent feeling in reality. It should be just the absence of of happiness. When human beings do not know the exact science behind happiness they coined the word and called it Dukkha.
The philosophy of coexistence has explain the term happiness and clearly define the science behind it and how by behaving in a human way we can all be happy. How from being resolved as a individual we can spread the the level of happiness to encompass all the 7.7 billion people inhabiting the planet now.
I have written random articles trying to look at various facets of life from many angles and would love if you could add your own colours to them and spread happiness with people whom you interact with.
